The Choking Hand from Monolith's One Unit Whole Blood.
Replaces the Lost Soul. Doesn't choke but I have modified it so that it crawls around on the floor instead of floating. Can be used alongside other mods by launching them together or implemented into other mods. Credit for the sprites goes to Monolith. Enjoy!
Doesn't work
it may only work on an earlier version of gzdoom or zdoom, I haven't tested it in a while
