Spell Description

This spell targets a qualifying class-acquired companion (excluding outsiders and undead). It permanently transforms the creature into a celestial (good deity), fiendish (evil deity), axiomatic (lawful neutral deity), or anarchic (chaotic neutral deity).

For familiars, template scaling (energy resistance, fast healing, damage reduction, and smite damage) uses your total character level instead of native Hit Dice. Axiomatic targets grant the linked minds ability solely to you. The spell requires a 500 XP cost.
