I'm going to be strictly using Quarterstaffs (main will be dreamspitter)
i'll be in Fire Stance the whole time, bladesworn transformation for additional +4 str and damage, power surge for another + 8
Taking slicing blow due to the lack of Wounding weapons available to blunt weapons
Exalted smite for x3 crit on stunned enemy
don't know if it's worth going for further str enhancement, cha enhancement, and wis enhancement tho

is it too squishy with 400-ish hp?
should i pick up cleave + greater cleave instead of slicing blow + skill focus?

inputs appreciated =\

Well the best HP advise I can give you is my ranger is about 430 HP when at 20 and my fighter hits about 530. And neither one of them would I want to have any less HP. In fact both of them I am working on raising the HP higher on. I would like to get another 30 HP or so on each of them.

i guess i can bump another 20 with Minos
and MAYBE if that's still not enough i'll actually do greensteel =(
but i wanna avoid greensteel if possible >___<
maybe if i go mountain stance for another + 2 con (+20 more hp?)
