I'm quite sure I'm reading this right, but it still doesn't sound right.
The 1st level Strength Domain power says:
Strength Surge (Sp): As a standard action, you can touch a creature to give it great strength. For 1 round, the target gains an enhancement bonus equal to 1/2 your cleric level (minimum +1) to melee attacks, combat maneuver checks that rely on Strength, Strength-based skills, and Strength checks. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Since this is an enhancement bonus to attack, it wouldn't stack with a magic weapon, but it would stack with Bull's Strength (an enhancement bonus to Strength, not to attack).
It just seems counter-intuitive to me. There's no errata I'm missing?
It would work with Bull Strength becase it enhances strength based checks but not your Strength.
to be honest im not sure why the bit about attacks is in there since i think its a standard action to activate. So its (standard action Rawr im strong) Followed by some feat of great strength.
Put one Cleric with Strength domain 5 feet behind the Croneman The Barbarian. Cleric takes standard action to boost Croneman. In his turn Croneman *SMASH*. Repeat until out of daily uses as needed.
Oh its touch i didnt notice that. thats a pretty good support ability. Especially if Croneman wants to Wrestle that troll :P
