Infernal calling

Infernal calling was a spell used to summon a devil.

Effects
A caster used this spell to summon a devil from the Nine Hells. The caster choose which devil they wished to summon during casting. The most powerful devil a caster could summon with this spell was a barbed devil or a bearded devil. A powerful caster with a high skill level or the talisman of the target devil was able to summon more powerful devils such as a cornugon.

The summoned devil was immediately hostile towards the caster and any creature around them. If the devil sensed that the caster was weaker then them, or the caster's concentration lapsed, it simply attacked and killed the caster then vanished. During the summoning, the caster attempted to command the devil to perform a task. If a devil agreed to do so, it usually meant that the task was in alignment with its own goals. If the caster knew the devil's true name, they could compel the devil to obey their command. Upon completing the task, the devil returned to the caster to report on its actions.

Components
In addition to verbal and somatic components, the spell required a material component, a ruby with a value of at least 999 gp.
