I had the idea to build a cleric of Korada, whose favored weapon is a unarmed strike, which means the cleric gets the improved unarmed strike according to this faq: http://paizo.com/paizo/faq/v5748nruor1gj#v5748eaic9r9j (I'll have to confirm this with the GM of the oncoming campaign, but I think/hope that will not be a problem (if it is, I can always take a level of monk or spend a feat on IUS)).
The real question is wether I can take the feat domain strike with the magic domain (which Korada has as well) and the hand of the acolyte power.
copy-paste: Domain Strike (Combat)
You unleash a domain power upon your enemy as part of your unarmed strike.
Prerequisites: Domain class feature, Improved Unarmed Strike.
Benefit: When you gain this feat, choose one domain-granted power that you can use to affect no more than one opponent. If you make a successful unarmed strike against an opponent, in addition to dealing your unarmed strike damage, you can use a swift action to deliver the effects of the chosen granted power to that opponent. Doing so provokes no attacks of opportunity.
Special: You can take this feat multiple times. Each time you take it, you apply it to a different qualifying domain power.
And:
Hand of the Acolyte (Su): You can cause your melee weapon to fly from your grasp and strike a foe before instantly returning. As a standard action, you can make a single attack using a melee weapon at a range of 30 feet. This attack is treated as a ranged attack with a thrown weapon, except that you add your Wisdom modifier to the attack roll instead of your Dexterity modifier (damage still relies on Strength). This ability cannot be used to perform a combat maneuver. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
So the question is: I'm not sure hand of the acolyte qualifies as 'you can use to affect no more than one opponent': does it affect your opponent or your weapon?
(And yes, I know that normally you'd have your weapon in your hand, which makes unarmed strike difficult, but I thought I'd hit with my on-hand and have a weapon in my off hand, or (better) have a twohanded weapon and use a free action to let one hand loose... alternatively, can hand of the acolyte let your unarmed strike fly from your grasp? :p)
A big flaw in the plan is that without monk levels unarmed damage is very low even with the IUS feat :(
