This pale creature resembles a human child with slug-white skin. Its black eyes are too knowing for their size, and its too-wide mouth is home to rot and ruin.

Slaymates are undead creatures given a semblance of life when a guardian's betrayal, either outright or through negligence, leads to death. A slaymate's appearance is a weird and twisted reflection of the form it had in life. Slaymates are highly prized by necromancers, and thus are rarely encountered alone but instead are found in the presence of evil spellcasters and others who dabble in necromancy. Many a slaymate can be found riding, papoose style, on the back of a necromancer who values the slaymate's special abilities.

A slaymate is about the height and weight of an eight-year-old human child.

Slaymates speak Common.
