I'm currently a lvl4 human and already have the following:

Toughness
TWF
Extend

Going to pick up the following (not in specific order):

ITWF
GTWF
Emp Heal (don't go into Emp vs. Emp Heal, I know what I want and why)
Max
Quicken

I would like to be able to pick up IC:Slash, but I'd have to drop something from the list above. I'm debating extend. It would be more hassle for spells like Divine Favor/Power with the short durations. Would it be worth trading that for IC? I wouldn't have enough BAB to get that until lvl11 so my buffs will be lasting longer anyway. Constructive input is appreciated. Thanks.
