# Immortal Creatures
The world of Infinite Terror is littered with a variety of undead creatures, varying in character from DND worlds to mythical worlds, but unless otherwise noted, they are all considered to have the following characteristics for rules purposes.
Vitality adjustment: undead creatures have no vicious damage slots, but their vitality is doubled. All traits that deal malevolent damage deal severe damage to them. They are destroyed as soon as their life slots are filled by critical damage.
Monster Unique: Undead creatures have no Intelligence and are not affected by Intelligence plus or minus, which also means they are immune to certain Intelligence counter or immunity abilities, which also means they are immune to mind effects. Note: If an undead creature has Intelligence (such as a sorcerer), it loses this feature.
Undead creatures are immune to toxins, paralysis, shock, disease, nausea, and instant death.
An undead creature does not need to sleep, which means it is also immune to sleep. It also does not need to eat or breathe. All immunities of undead creatures are C-rank. An undead creature cannot be resurrected once it dies unless it can revert in time. Usually undead has the dark creature trait.
