Comments:
A wild idea I had for a while, previously attempted to TAS this without getting the armor and let the corpse slide into the exit, which just barely failed despite many tries and brute forcing (but should be possible). I poke the arch-vile so that it retaliates beyond its normal attack range, use the rocket to get enough momentum, and barely survive thanks to the armor.
