Challenge Rating: ?

You hear a mass of clicking noises coming from the darkened window. You The window looks like it’s beginning to melt, and a faint smell of acid is evident.. Through it pours a swarm of tiny black forms. They resemble large spiders but have tougher exoskeletons and seem to be dripping acid from their bodies.

Demon diggers are small, mindless spider-like creatures created by one of the demon lords to function as living diggers. They attach themselves to a surface and then secrete acid, eating away at rock, metal, or whatever is in their way.

Combat
Demon diggers usually ignore other creatures in favor of continuing their assigned tasks, but if disturbed they will counterattack, usually exhaling an acid breath at the offenders before swarming over them. They tend to reserve their transmutate rock to mud and metal melt spell-like abilities for their excavation work (if they have not already used them that day), but will employ them if necessary.

Spell-like Abilties
1/day-Transmutate rock to mud, 3/day-Metal melt (DC 14), acid breath (DC 13), melf’s acid arrow (DC 12) (caster level 5th) Save DCs are charisma based.
