As a standard action, you can unleash an acid dart targeting any foe within 30 feet as a ranged touch attack. This acid dart deals 1d6 points of acid damage + 1 point for every two cleric levels you possess. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.

At 6th level, you gain resist acid 10. This resistance increases to 20 at 12th level.

At 20th level, you gain immunity to acid.

At 1st level, you can touch one weapon and enhance it with acidic potency. For 1 minute, this weapon emits acrid fumes that deal an additional 1d4 points of acid damage with each strike.

At 10th level, you can touch an ally and harden its armor or clothing. For 1 minute, the ally gains DR 1/-. For every 2 levels beyond 10th, this DR increases by 1 (to a maximum of DR 5/- at 18th level). This doesn't stack with any other damage resistance or reduction.
