Just cooked up a domain focused on disease. Intended for NPC followers of a Demon Lord. I wanted to solicit thoughts. Is this appropriate? Balanced? Does balance matter for NPC domains?
Pestilence Domain
Bleeding Touch (Sp): As a melee touch attack, you can cause a living creature to take 1d6 points of damage per round. This effect persists for a number of rounds equal to 1/2 your cleric level (minimum 1) or until stopped with a DC 15 Heal check or any spell or effect that heals damage. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Aura of Decay (Su): At 8th level, you can emit a 30-foot aura of decay as a standard action. Living creatures in this aura (except you) take 1d6 points of damage per round as their flesh rots. They also take a cumulative –1 penalty to Strength each round they remain in the aura. Once outside the aura, the penalty fades at the rate of –1 per round, but it begins building again if they reenter the aura. Plant creatures take 2d6 points of damage per round. You can use this ability for a number of rounds per day equal to your cleric level. These rounds do not need to be consecutive.
