ABSORB OBJECT

2nd-level transmutation (ritual) (sorcerer, warlock, wizard)

Casting Time: 1 action

Range: Touch

Components: V, S

Duration: 1 hour

You touch an object weighing 5 pounds or less whose longest dimension is 4 feet or less. The object cannot be one worn or carried by another creature. The spell causes the item to disappear, and a red blotch shaped like the item appears on your body in a place of your choice.

If the item is coated in a liquid such as a poison or oil, then those liquids don’t dry, retaining their potency for the duration of the spell.

Any time thereafter, you can use a bonus action to touch the blotch, causing the item to instantly appear in your hand and ending the spell.

If the item is a weapon that you are proficient with, then you can feint with it when you retrieve it from its hiding place, choosing one creature within 5 feet of you as your target. You have advantage on your next attack roll against that creature this turn. If that attack hits, you add 1d6 to the attack’s damage roll.

At Higher Levels. If you cast this spell using a spell slot of 4th level or higher, the duration is 8 hours. If you use a spell slot of 6th level or higher, the duration is 24 hours. If you use an 8th level spell slot, the spell lasts until it is dispelled.

REFLEXIVE TELEKINESIS

6th-level transmutation (sorcerer, wizard)

Casting Time: 1 action

Range: Self (5-foot radius)

Components: V, S

Duration: Concentration, up to 10 minutes

For the duration, you can move creatures and objects that threaten you by thought (no action required, but you must still be able to take reactions), causing the effects below.

Creatures. You can try to move a Medium or smaller creature you can see whenever it moves within range or starts its turn there. Make an ability check with your spellcasting ability modifier contested by the creature’s Strength check. If you win the contest, you push the creature up to 15 feet in any direction, including upwards, and the creature is knocked prone.

Objects. You can try move the weapon or piece of ammunition whenever a weapon attack is made against you by a creature you can see (even if they aren’t within the spell’s range). The object can weigh up to 100 pounds and must be small enough for you to hold. Make an ability check with your spellcasting ability modifier contested by the attack roll against you, you make the roll with the +10 bonus if object isn’t being held by a creature (such as a piece of ammunition or thrown weapon). If you win the contest, the attack against you misses, and if the object was being held then it is pulled away from that creature.

In addition, you can then immediately make a ranged weapon attack against a target you can see within 60 feet of you, using the weapon or piece of ammunition you targeted. You make this attack using your spellcasting ability modifier and with proficiency, regardless of your weapon proficiencies. Being within 5 feet of a hostile creature doesn't impose disadvantage on this attack roll.

PRISMATIC EYE

8th-level evocation (sorcerer, wizard)

Casting Time: 1 action

Range: 150 feet

Components: V, S

Duration: 1 minute

You summon a fist-sized eyeball with a prismatic iris that can fire rays of light. The eye appears in an unoccupied space that you can see within range and lasts the duration.

You mentally receive visual information from the eye, which has normal vision and darkvision out to 60 feet. The eye can look in every direction.

The eye is a Tiny object that has an AC 20. The eye can’t be destroyed by damage and can’t be entirely dispelled by dispel magic. However, certain conditions can cause the eye to lose its rays, as described below. Once the eye has lost all seven of its rays, the spell ends.

When you cast the spell – and as a bonus action on each of your turns thereafter – you can move the eye up to 60 feet, but not beyond the range of the spell, and cause it to fire a random beam at creature you can see within 60 feet of the eye. The target must make a Dexterity saving throw. Roll a d8 to determine which color ray is used. If you roll a ray that has been lost, nothing happens.

Red. The target takes 10d6 fire damage on a failed save, or half as much damage on a successful one. This ray is lost if the eye takes at least 10 cold damage.

Orange. The target takes 10d6 acid damage on a failed save, or half as much damage on a successful one. This ray is lost if the eye is subjected to a strong wind.

Yellow. The target takes 10d6 lightning damage on a failed save, or half as much damage on a successful one. This ray is lost if the eye takes at least 25 force damage.

Green. The target takes 10d6 poison damage on a failed save, or half as much damage on a successful one. This ray is lost if the eye is in magical darkness created by a darkness spell or a similar spell of equal or higher level.

Blue. The target takes 10d6 cold damage on a failed save, or half as much damage on a successful one. This ray is lost if the eye takes at least 10 fire damage.

Indigo. On a failed save, the target is restrained. It must then make a Constitution saving throw at the end of each of its turns. If it successfully saves three times, the spell ends. If it fails its save three times, it permanently turns to stone and is subjected to the petrified condition. The successes and failures don't need to be consecutive; keep track of both until the target collects three of a kind. This ray is lost if the eye is in bright light shed by a daylight spell or a similar spell of equal or higher level.

Violet. On a failed save, the target is blinded. It must then make a Wisdom saving throw at the start of your next turn. A successful save ends the blindness. If it fails that save, the creature is transported to another plane of existence of the GM's choosing and is no longer blinded. (Typically, a creature that is on a plane that isn't its home plane is banished home, while other creatures are usually cast into the Astral or Ethereal planes.) This ray is lost if the eye is targeted by a dispel magic spell or a similar spell of equal or higher level that can end spells and magical effects.

Special. The eye fires two rays. The rays either strike the same target or you can choose for one ray to target another creature within 60 feet of the eye. Roll twice more, rerolling any 8.

At Higher Levels. If you cast this spell using a 9th level spell slot, the duration is 10 minutes and there is no limit to how far away from you the eye can move.

SOLID FOG

6th-level conjuration (druid, sorcerer, wizard)

Casting Time: 1 action

Range: 90 feet

Components: V, S

Duration: Concentration, up to 10 minutes

You create a 20 foot radius, 10 foot high cylinder of thick fog centred on a point within range. The sphere spreads around corners, its area is heavily obscured, and every foot of movement though it costs 2 extra feet. It lasts the duration or until a strong wind (at least 20 miles per hour) disperses it, which takes up to 4 rounds and ends the spell. Extremely strong winds can cause the fog to disperse faster, as determined by the DM.

You and any other creature you designate when you cast the spell are immune to the effects of the fog. To such creatures, and to those with truesight, the fog obscures nothing and looks like a soft mist, with motes of light floating in the air.

The fog moves up to 10 feet in a direction you choose at the start of each of your turns, rolling along the surface of the ground. When it moves, each creature in its space must succeed on a DC 10 Strength saving throw or be moved with it. The vapors, being heavier than air, sink to the lowest level of the land, even pouring down openings. If the cloud falls on a creature, it must succeed on a DC 10 Strength saving throw or be knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the radius of the fog cloud increases by 20 feet for each slot level above 8th.

STAFF OF THE IMPALER

Staff, uncommon (requires attunement)

This staff has properties associated with three different buttons that are set in a row along the haft. You can press one of the staff's three buttons as a bonus action. A button's effect lasts until you push a different button or until you push the same button again, which causes the staff to revert to its normal form. Pressing a button causes the haft of the staff to change length and a spear-like point to spring from the staff’s tip, transforming the staff into a magic weapon that grants a +1 bonus to attack and damage rolls with it.

Button - Weapon 1 - Spear 2 - Pike 3 - Lance

WITHERING POSSESSION

7th-level necromancy (warlock, wizard)

Casting Time: 1 action

Range: 30 feet

Components: V, S

Duration: 1 hour

This spell summons an invisible and incorporeal spirit that can possess targets at your command until the spell ends. The spirit occupies your space and moves with you while it isn’t possessing a creature. It can’t be targeted by any attack, spell, or other effect, except ones that turn undead, it can’t attack, has an Intelligence of 10, and a Wisdom and Charisma equal to your spellcasting ability score.

This spell summons an invisible and incorporeal spirit that can possess targets at your command until the spell ends. The spirit occupies your space and moves with you while it isn’t possessing a creature. It can’t be targeted by any attack, spell, or other effect, except ones that banish or turn undead, it can’t attack, has an Intelligence of 10, and a Wisdom and Charisma equal to your spellcasting ability score.

When you cast the spell and as a bonus action on your subsequent turns, you can mentally command the spirit to attempt to possess a humanoid you can see within range. Creatures warded by a protection from evil and good or magic circle spell can’t be possessed, and you can’t target a creature again if it has already succeeded on a saving throw against this casting of withering possession.

The target must succeed a Charisma saving throw or be possessed by the spirit. While possessed, the target is incapacitated and loses control of its body. The spirit now controls the body but doesn’t deprive the target of awareness. The spirit uses the possessed target’s statistics, except it retains its Intelligence, Wisdom, and Charisma, and it doesn’t gain access to the target’s knowledge, class features, or proficiencies. At the end of each of its turns, the target repeats the saving throw, taking 4d6 necrotic damage on a failed save, or ending the possession on a successful one.

On each of your turns, you can use a bonus action to mentally command the spirit possessing a creature if it is within 60 feet of you. You decide what action the creature will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the creature only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete.

The possession lasts the body drops to 0 hit points, you end it as a bonus action, or the spirit is turned or forced out by an effect like the dispel evil and good spell. This spell ends early if the spirit turned or forced out of a creature, but it can’t be dispelled by dispel magic.

SWORD OF ANNIHILATION

Weapon (longsword), legendary (requires attunement by a creature with proficiency in Arcana)

The black blade of this sword is fashioned from a sphere of annihilation, a hole in the multiverse stabilized by a magical field surrounding it. A talisman of the sphere resembling a wailing devil face is fashioned into the tarnished bronze hilt of the sword, with the blade extending from its open mouth.

When you attack with this magic weapon, you must use your Intelligence modifier, instead of Strength, for the attack and damage rolls. In addition, you can attack twice with the sword, instead of once, when you take the Attack action on your turn. You ignore this benefit if you already have a feature, like Extra Attack, that gives you extra attacks. On a hit, the sword deals 4d10 force damage instead of its normal damage die.

When you attack an object with this sword and hit, maximize your weapon damage dice against the target. Artifacts are the exception. Unless an artifact is susceptible to damage from a sphere of annihilation, the blade passes right through an artifact, leaving it unscathed.

When you attack a creature with this weapon and roll a 20 on the attack roll, that target takes an extra 2d10 force damage. Then roll another d20. If you roll a 20 you lop off one of the target's limbs, with the effect of such loss determined by the DM. If the creature has no limb to sever, you lop off a portion of its body instead.

If the sword comes into contact with a planar portal, such as that created by the gate spell, or an extradimensional space, such as that within a portable hole, the DM determines randomly what happens, using the following table.

d100 - Result 01-50 - The sword is destroyed. 51-85 - The sword moves through the portal or into the extradimensional space. 86-00 - A spatial rift sends each creature and object within 180 feet of the sword, including the sword, to a random plane of existence.

METALLIC DRAGON’S BREATH

5th-level transmutation (cleric, paladin, sorcerer, wizard)

Casting Time: 1 bonus action

Range: Touch

Components: V, S, M (a piece of platinum worth 10 gp)

Duration: Concentration, up to 10 minutes

You touch one willing creature and imbue it with the power to spew magical energy from its mouth, provided it has one. Once before the spell ends, the creature can use an action to exhale energy in a 30-foot cone, choosing one of the following options.

Sleep Breath. Each creature in the cone must succeed on a Constitution saving throw or fall unconscious for the duration. This effect ends for a creature if the creature takes damage or someone uses an action to wake it.

Repulsion Breath. Each creature in the cone must succeed on a Strength saving throw or be pushed 40 feet away from you and be knocked prone.

Slowing Breath. Each creature in that area must succeed on a Constitution saving throw. On a failed save, the creature can't use reactions, its speed is halved, and it can't make more than one attack on its turn. In addition, the creature can use either an action or a bonus action on its turn, but not both. These effects last for 1 minute or until the spell ends. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself with a successful save.

Weakening Breath. Each creature in that area must succeed on a Strength saving throw or have disadvantage on Strength-based attack rolls, Strength checks, and Strength saving throws for 1 minute or until the spell ends. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Paralyzing Breath. Each creature in that area must succeed on a Constitution saving throw or be paralyzed until the start of your next turn.

DELAYED DISPLACEMENT

3rd-level illusion (artificer, bard, sorcerer, warlock, wizard)

Casting Time: 1 action

Range: Self

Components: V, S

Duration: 10 minutes

You project a magical illusion that makes you appear to be trailing behind your actual location when you move, causing opportunity attacks against you to have disadvantage. Additionally, if you move at least 10 feet beforehand, you gain advantage on your first attack roll each turn.

If you take damage, the spell is suppressed until the start of your next turn. This spell is also suppressed while you are incapacitated, restrained, or otherwise unable to move.

In addition, if you teleport while under the effect of this spell, you become invisible while the illusion of you remains where in the space that you left, mimicking your movement and actions. This effect lasts until the start of your next turn.

A creature is unaffected by this spell if it can’t see, if it relies on senses other than sight, such as blindsight, or if it can perceive illusions as false, as with truesight.

[forge-onward]

THUNDER FIELD

5th-level evocation (bard, druid, sorcerer, wizard)

Casting Time: 1 action

Range: 120 feet

Components: V, S

Duration: Concentration, up to 10 minutes

You create a 15-feet-radius sphere of magic centered on a point you can see within range. Until the spell ends, the sphere prevents sound from passing through the edges of its radius and releases waves of thunderous force. When you cast the spell, you determine if these waves are directed towards the inside or outside of the sphere, choosing from either of the following effects:

Outwards. When a creature outside the sphere moves within 15 feet of it for the first time on a turn or starts its turn there, it must succeed on a Constitution saving throw. On a failed save, a creature takes 5d8 thunder damage and is pushed 10 feet away from the sphere. On a successful save, the creature takes half as much damage and isn’t pushed.

In addition, unsecured objects outside of the sphere that are completely within 15 feet of it are automatically pushed 10 feet away from the sphere by the spell’s effect, and the sphere emits a constant thunderous roar audible out to 300 feet.

Inwards. When a creature moves into the sphere for the first time on a turn or starts its turn there, it must succeed on a Constitution saving throw. On a failed save, a creature takes 5d8 thunder damage, is knocked prone, and is deafened for 1 minute. On a successful save, the creature takes half as much damage and isn’t knocked prone or deafened.

In addition, no sound created within the sphere can be heard outside of it.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 6th.

POTION OF MANA

Potion, rarity varies

When you drink this potion, you regain your highest level expended spell slot, up to a certain level. The maximum level of the expended spell slot depends on the potion’s rarity, as shown on the table below. Whatever its potency, the potion's blue liquid glimmers when agitated.

Each time you subsequently drink a potion of mana before finishing a long rest, there is a 20 percent cumulative chance of instead creating a magical explosion within you, causing you to take 1d10 force damage for each level of the maximum slot level. Thus, an uncommon potion of mana would deal 2d10 force damage.

Potion of … - Rarity - Spell Slot Level Mana - Uncommon - 2nd Greater Mana - Rare - 4th Superior Mana - Very rare - 6th Supreme Mana - Legendary - 8th

[forge-onward]

HUNTER'S OIL

Potion, uncommon

Hunter's oil is a rare concoction used by monster hunters to find and kill their prey. This glass jar, 3 inches in diameter, contains 1d4 + 1 doses of a crimson, gelatinous oil that smells strongly of copper. The jar and its contents weigh 1/2 pound. Each hunter's oil is designed for a particular kind of creature; for example, undead, shapechangers, or lycanthropes.

The oil gives off a faint, red glow when it comes within 120 feet of the type of creature. It can also coat one weapon or up to 5 pieces of ammunition. Applying the oil takes 1 minute, making the coated item magical for 1 hour.

A creature that ingests the oil must succeed on a DC 15 Constitution saving throw or for next hour, they are poisoned whenever they are within 120 feet of the specific type of creature.

[forge-onward]

STAFF OF FIERY POWER

Staff, very rare (requires attunement by a sorcerer, warlock, or wizard)

This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. While holding it, you gain resistance to fire damage and a +2 bonus to the damage roll of any spell you cast that deals fire damage.

The staff has 20 charges for the following properties. The staff regains 2d8 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff retains its +2 bonus to attack and damage roll but loses all other properties. On a 20, the staff regain 1d8 + 2 charges.

Fiery Strike. When you hit with a melee attack using the staff, you can expend 1 charge to deal an extra 1d6 fire damage to the target.

Spells. While holding this staff, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC and spell attack bonus: brightbolt (6 charges), burning hands (1 charge), conjure elemental (fire elementals only, 5 charges), fireball (3 charges), firebind (3 charges), flaming sphere (2 charges), scorching ray (2 charges), and wall of fire (4 charges)

Retributive Strike. You can use an action to break the staff over your knee or against a solid surface, performing a retributive strike. The staff is destroyed and releases its remaining magic in an explosion that expands to fill a 30-foot-radius sphere centered on it.

You have a 50 percent chance to instantly travel to the Elemental Plane of Fire, avoiding the explosion. If you fail to avoid the effect, you take fire damage equal to 16 x the number of charges in the staff. Every other creature in the area must make a DC 17 Dexterity saving throw. On a failed save. a creature take an amount of damage based on how far away it is from the point of origin, as shown in the following table. On a successful save, a creature takes half as much damage.

Distance from Origin - Damage 10 ft. away or closer - 8 x the number of charges in the staff 11 to 20 ft. away - 6 x the number of charges in the staff 21 to 30ft. away - 4 x the number of charges in the staff

3rd-level evocation (artificer, sorcerer, wizard)

Casting Time: 1 action

Range: 60 feet

Components: V, S, M (a vial of acid worth at least 25gp)

Duration: Concentration, up to 10 minutes

You create a line of acid on solid surface within range, creating a wall of acidic fumes above it. You can make the wall up to 60 feet long and 5 feet thick or a ringed wall up to 20 feet in diameter and 5 feet thick. The wall of fumes extends 30 feet high, its area is heavily obscured, and it lasts for the duration.

When the wall appears, each creature within its area must make a Dexterity saving throw, and does so with advantage if it is flying. On a failed save, a creature takes 5d4 acid damage, or half as much damage on a successful save.

The first time a creature enters the area on a turn or ends its turn there, the creature takes 5d4 acid damage. At the end of each of your turns, the acid damages objects in the area that aren’t being worn or carried, and deals maximum damage to the ground in the area.

Wind of moderate or greater speed (at least 10 miles per hour) disperses the fumes, but they return 1 round after the wind stops. While dispersed, creatures and objects can still be damaged by the acid if they are on the ground in the spell’s area.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 2d4 for each slot level above 3rd.

GMS Core Bonus

Inspired by Weight Control from Armored Core

IMPROVED HEAVY ARMAMENT

By overclocking power and strengthening systems, you can mount an additional heavy weapon, exceeding factory recommendations and overburdening the frame. However, this extra weapon can be purged at a moment’s notice with explosive decoupling.

If your mech has fewer than three mounts (excluding integrated mounts), it gains an additional HEAVY mount. While you have a weapon attached to this mount, you are SLOWED, however, you can destroy that weapon as a free action.
