Hey, i just had a quick question. If a cleric were to take the artifice domain and use the domain power:
Artificer's Touch (Sp): You can cast mending at will, using your cleric level as the caster level to repair damaged objects. In addition, you can cause damage to objects and construct creatures by striking them with a melee touch attack. Objects and constructs take 1d6 points of damage +1 for every two cleric levels you possess. This attack bypasses an amount of damage reduction and hardness equal to your cleric level. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Would this provoke an attack of opportunity if used to attack a weapon? Therefore needing Improved sunder. Also would the domain power Metal fists, would it provoke attacks of opportunity to attack a weapon? i would assume so on this one but just making sure:
Metal Fist (Su): As a swift action, you can turn your fists into metal for 1 round, allowing you to make unarmed strikes that deal 1d6 points of bludgeoning damage plus your Strength modifier. These unarmed strikes do not provoke attacks of opportunity, but attacking with both uses the two-weapon fighting rules as normal. In addition, these unarmed strikes ignore the hardness of items with a hardness of 10 or less. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Artificer's Touch is a spell-like ability, so it will provoke AoOs no matter what as long as you are in combat and adjacent to an enemy. I don't think you can combine this ability with the Improved Sunder feat as the ability is not a sunder combat maneuver.
Metal Fist, however, turns your fists into bludgeoning weapons. You can then use your fists to make a sunder attempt. This action would still provoke an AoO, but in this case the Improved Sunder feat would deny the enemy the AoO.
