Associated Domain: Animal.
Replacement Power: The domain spells provided by the Insect domain affect vermin rather than animals, treating them as if they were not immune to spells with the mind-affecting descriptor. Any such spell that allows a Will save can instead be negated by the target vermin with a successful Fortitude save at the same DC. The following granted power replaces the speak with animals power of the Animal domain.
As a swift action, you can grow an exoskeleton that grants you a +1 enhancement bonus to your natural armor and 1d4 temporary hit points + 1 for every 2 cleric levels you have. The natural armor bonus increases by 1 for every 5 cleric levels you have. The exoskeleton retracts after 1 round, ending its benefits. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
