Domain

From NWNWiki

Clerics receive two domains, which give them access to a special domain power and/or additional spells.

Details about the 19 domains are on the cleric domain category page.

[edit] Domains and turning outsiders

Outsiders get turn resistance equal to their spell resistance rating (only clerics of the good or evil domains may turn them without the planar turning feat). If you have the planar turning feat they are weakened and only have 1/2 their spell resistance as turn resistance.
