Sleep resistance
Sleep resistance is an intrinsic which prevents you from being put to sleep by wands of sleep, potions of sleeping, sleeping gas traps, and orange dragon's breath attack, or when wearing an amulet of restful sleep. When you acquire the sleep resistance intrinsic, you get the message "You feel (wide) awake!" It can be acquired by:
- Playing a Monk, or an Elf of level 4 or higher
- Eating a monster which confers the intrinsic (e.g. elves of all kinds, homunculi, gelatinous cubes)
- Being polymorphed into a naturally sleep-resistant monster
Strategy
Sleeping gas traps are plentiful in Gehennom, so sleep resistance is a high priority. However, elves are quite common in the upper dungeon, and can be safely eaten by anyone but an elf player, who gains intrinsic sleep resistance anyways, so getting sleep resistance is not difficult.
Obtaining
Different monsters have the ability to confer this instrinsic upon eating. The full list is below. The percent chance refers to the chance of gaining this instrinsic upon completely eating the corpse. Only the gelatinous cube is safe for vegetarians or vegans. Some of the corpses may be hazardous to eat; the possible danger is noted in the Danger column.
