This domain complements the Blight Master multiclass archetype.
Granted Powers: The bond you have with the pests and parasites force them to heed your every command, and grant you an endless source of power.
Vermin Empathy (Su): You gain the druid’s wild empathy ability, except that you can only improve the attitude of vermin, not animals or magical beasts. Vermin have a starting attitude of unfriendly.
Worm Eater (Su): At 1st level, as full-round action, you can summon and consume 1 pound of beetles, cockroaches, rot grubs, or some other fine or diminutive vermin. Once consumed, you gain a +2 sacred (or profane) bonus on all saving throws against disease and effects that cause the sickened or nauseated conditions for a number of rounds equal to your cleric level + your Charisma modifier. You can use this power a number of times per day equal to 3 + your Wisdom modifier.
Parasitic Infestation (Su): At 8th level, once per day with a successful touch attack, you can infest a living creature with tiny parasites unless the target makes a Fortitude save (DC 10 + 1/2 your cleric level + your Constitution modifier). On a failed save, the target takes 1d4 points of Constitution damage per round as the parasites burrow through and consume its flesh. This infestation persists for 10 rounds, during which time the target is staggered and you are healed for 2 hit points for every point of Constitution damage dealt to the target. If this heals you above your normal hit point total, you gain the extra hit points as temporary hit points for 10 minutes. Any spell or effect that removes disease instantly ends the parasitic infestation. Immunity to disease offers no defense against this ability.
