I'm going to be doing a GR on my cleric fighter dip RealSoon(TM) and I'm probaly going to take Power Attack for my fighter-class feat, but while I am certainly a melee-capable cleric, my melee DPS isn't that stellar, and I'm concerned tha PA may cause me to miss enough more that it won't really be that great.
Is there a critical to-hit modifier to using PA to best effect?
Thanks,
