While the adherer is described as having a mummy-like appearance, it is not technically undead. Instead it is a humanoid covered with loose folds of white skin that is said to secrete an adhesive substance which causes weapons employed against it to be reduced in effectiveness and to stick to its body.
The creature appeared in the following publications:
- First appeared as the gluey in White Dwarf #7 (June/July 1978).
- The original first edition Fiend Folio (1981).
- The second edition Fiend Folio Monstrous Compendium supplement (1992).
- The Tome of Horrors (2002) from Necromancer Games.
- Fully detailed in Paizo Publishing's book Misfit Monsters Redeemed (2010), on pages 4–9.
