Wights are humanoids who rise as undead due to necromancy, a violent death, or an extremely malevolent personality. In some cases, a wight arises when an evil undead spirit permanently bonds with a corpse, often the corpse of a slain warrior. They are barely recognizable to those who knew them in life; their flesh is twisted by evil and undeath, the eyes burn with hatred, and the teeth become beast-like. In some ways, a wight bridges the gap between a ghoul and a spectre—a warped animated corpse whose touch steals living energy.
As undead, wights do not need to breathe, so they are sometimes found underwater, though they are not particularly good swimmers unless they were originally swimming creatures such as aquatic elves or merfolk. Underwater wights prefer low-ceilinged caves where their limited swimming isn’t as much of a liability.
