Lesser devils

A lesser devil's service can never run past one hour. The Black Magic spell Summon Lesser Demon/Devil calls one. The lesser devils listed are gargoyles and the bat horin.

Like all devils it comes from Hades, the nine hells, and keeps faithfully to the lawful Order of Ascendancy under Asmodeus. Summoners must be firm: devils aid those of like alignment and purpose but scorn the incompetent and anyone in league with demons, and they attack demons themselves on sight, and every devil dreads the power of good and cannot abide holy symbols. A flaw in the protective circle or triangle frees it to enslave or kill its summoner, and ordering more than its kind owes breaks the pact at once.
