An arcanaloth is one of the jackal-headed scribes, record-keepers, negotiators, and deal-makers of the yugoloths. As such, they are grasping, wheedling manipulators, but at least they’re generally true to their word. An arcanaloth has humanoid form but the head of a jackal or dog. It dresses finely but is businesslike and abrupt, if not downright surly. Arcanaloths can speak and write any language.

Arcanaloths are weak in melee, but they are powerful spellcasters.
