Flavor

The priest tears open a glowing portal to another plane and calls a mighty being through it.

Mechanics

Opens a planar gate and summons a specific powerful named entity (often a being aligned with the priest's faith) which arrives and may aid, bargain, or react per its nature; calling something far stronger than the priest is exceedingly dangerous. The gate is brief. The true name/identity is the key. Among the most powerful and risky spells. : the holy symbol.
