Creo Corpus magic generally leans into creo’s themes of improvement rather than strict creation. Creo Corpus magic can heal and improve physical attributes. However, for the sake of being weird, I have included a suite of spells for the prospective necromancer.
Ressurectionist’s Aid
Level 25 Creo (Muto) Corpus
Range: Touch Duration: Sun Target: Individual
Carefully reading over a diagram depicting and labelling parts of the human body, the caster brings their hands over a prepared area. A human corpse grows from bones to flesh before them. All of the corpse’s organs are color coded for humors and labelled in Latin, as are all of its bones.
(Base 5, +2 Sun, +1 Touch, +1 Muto Requisite)
Conjuration of the Spying Hand
Level 30 Creo (Muto) Corpus
Range: Touch Duration: Sun Target: Part
The caster makes a sweeping gesture at one of their own hands from wrist upwards while incanting. A human hand, unattached to any arm and resembling the caster’s, appears in their own. As the spell ends, a line is drawn upon the back of the hand; a human eye opens up.
This spell does not, itself, animate the spying hand- but any hand so animated is capable of sight.
Conjuration of Grasping Arms
Level 35 Creo (Muto, Rego) Corpus
Range: Voice Duration: Concentration Target: Group, Part
Dark and horrible words rip from the caster’s mouth and into the ground. Bones grow forth from the ground, and then swiftly wrap themselves in flesh. A dozen human arms form, divided between different targets within range as the caster wishes. These arms grasp at anyone or anything the caster so desires with an effective Strength of +0.
Once created, the arms are not capable of moving from the place they sprouted. If removed, they transform into grey ash.
When the caster ceases to concentrate, the arms release their hold and then turn into grey ash.
Both Conjuration of the Spying Hand and Conjuration of Grasping Hands could be created as momentary rituals that permanently create human body parts. Conjuration of the Spying Hand would be level 20; Conjuration of Grasping Hands would be level 30.
An enterprising necromancer would need to develop Charm Against Putrefaction [CrCo 5] (Core, pg 129), to preserve these creations from rot, but would otherwise be able to use them as desired.
