it took me a few minutes this time versus a few hours the first time. the biggest thing is learning the pattern of her green mode bullets. once you have that down, it just comes down to avoiding her red attacks (which i’m pretty atrocious at dodging honestly). the most important thing is dealing damage quickly because the fight only gets worse the longer it goes on for.
with that in mind, here’s some tips!
if you want a bit of extra survivability for the fight, grind glyde in snowdin forest.
doggo/dogi/lesser dog/greater dog (everyone who would be at grillby’s) must be killed, but the other enemies (ice cap, snowdrake, etc) can be fled from
if you only kill glyde besides the must kill enemies, you should hit lv 10 before you reach snowdin
please note that glydes start taking AGES to appear as more enemies are killed -- i think it can take up to about 16 minutes
make use of the walking and then alt tabbing thing so that frisk walks in place in order to encounter glyde
don’t worry if the save point message changes to “that comedian...” -- it replaces your kill counter but the counter is still there. once everything is dead, you’ll get the “determination” message as usual and the “but nobody came” encounters
after the waterfall enemies are killed, you’ll probabaly reach lv 12 if you’ve been killing glydes
without glyde grinding, playing normally would probably leave you at about lv 10 by the time you get to undyne
i’m not really sure how worth it the glyde grinding is, now that i’ve tried it. you end up with about 10 extra hp, which is really nice, but the grinding takes AGES.
keep the snowman pieces for this fight -- they’re only barely better than legendary heroes so they’re not worth keeping for sans
try to avoid using the pie in this fight as it WILL help with sans later
otherwise, fill up your inventory with cinnamon bunnies when can be stolen for free at snowdin (put a few extra in a box when you get there because why not, they’re free)
spider cider from the ruins is slightly better than cinnamon bunnies, but not especially vital; astronaut food is worse than cinnamon bunnies
equip the ballet shoes and the cloudy glasses
the ballet shoes give you the most damage possible, which is vital for ending this battle quickly
the torn notebook makes you hit around 1,100 damage on average versus the ballet shoes’ 1,600+ on average
the cloudy glasses give you i-frames which are absolutely vital unless you’re confident you won’t be hit more than once in an attack
the i-frames are ridiculously useful for every one of her attacks, but especially the fast-paced green attack bullets
bring your three snowman pieces, your spider ciders, and your cinnamon bunnies. the sea tea is not necessary. try not to use your pie (sans is doable without it but he’s a much bigger challenge) equip the ballet shoes and the cloudy glasses.
battle against a true hero:
avoid checking undyne or doing anything besides attacking
the fight follows the same order of attacks with the same patterns every time you do it
the longer the fight goes on, the worse the attacks will get
eventually, undyne will stop using green mode and only do grueling red mode attacks
heal at about 20hp unless you’re confident you can survive with 10hp
save your snowman pieces for when you have barely any hp left
try to make every attack count (make sure all your hits connect in the middle for the most damage possible) -- the more damage you do, the shorter the fight is, and the shorter the fight is, the easier it’ll be
turn 1: green attack. begins similarly to normal undyne’s first attack, but after the first few slow bullets much faster ones come from different sides
turn 2: green attack. slow bullets that come closely together. keep an eye on which arrow is red.
turn 3: red attack. arrows come from the outside of the bullet board and in a straight line in your direction.
turn 4: red attack. the bullet board is tiny and spears strike in a random order from below. relatively slow.
turn 5: green attack. DON’T look at the red arrows here as they ARE NOT the ones that will hit you next. this particular attack lies to you. judge which one will hit you first based on how close it is to you. this is the only time i’ve notice the arrow colours lying.
turn 6: green attack. most of the bullets come from above with one coming from the sides or bottom periodically. you must point back upwards immediately after getting one of the stray bullets or you’ll be hit.
turn 7: green attack. the yellow arrows make an appearance towards the end of this attack.
turn 8: red attack. the bullet board is huge. spears circle you and close in around you. try to avoid them by going to the sides and only moving up and down slightly as you need to.
turn 9: red attack. same as turn 8.
turn 10: green attack. lots of yellow arrows at first followed by normal arrows, followed by more yellow arrows. it’s easy to take a lot of damage here. even if you do, just heal up and things will be fine.
turn 11: green attack. a mixture between blue and yellow arrows.
turn 12: green attack. one blue arrow followed by one yellow arrow, from different sides, over and over. becomes easy to handle with a little practice.
turn 13: green attack. more slow arrows. more difficult than turn 2.
turn 14: red attack. the bullet board is huge. instead of the spears circling around like in turn 8, the arrows appear and close in very quickly. constantly move in a kind of large circle around the bullet board in order to avoid all the spears.
turn 15: red attack. similar to turn 8.
turn 16: red attack. similar to turn 3 but much faster.
turn 17: red attack. similar to turn 4 but the spears strike upwards a lot faster.
turn 18: similar to turn 14. the arrows close in extremely fast.
turn 19: similar to turn 8/15. the arrows circle and close in relatively fast.
turn 20: similar to turn 3/16. fast.
turn 21+: ???? i think it just switches between red attacks for the rest of the fight.
although i’m not positive that the red attacks always happen at the same time, the green attacks ALWAYS happen in the same order and in the same pattern. if you can learn the green attack patterns, you just need to practice avoiding the red attacks. it can take a lot of hours of practice, but once you’re able to do it, it’s kind of like riding a bike!
