Spider domain

The Spider domain was a deity domain that granted divine spellcasters spider-themed spells and powers.

Powers
A priest with this domain gained the ability to rebuke and command spiders much as an evil cleric rebuked and commanded undead.

Spells
At first, a priest with this domain could use spider climb to walk on walls and ceilings. As they advanced, they could summon swarms of spiders to attack at their command with summon swarm, insect plague, and creeping doom. They could also create a spider mount with phantom steed; enlarge spiders, centipedes, and scorpions with giant vermin; and turn rocks into spiders stone spiders. Finally, they could forcibly transform other people into spiders, with spider curse turning another being into an obedient drider-like creature, and spider shapes turning multiple willing beings into monstrous spiders.
