Level 12 (Fighter)
*Feat: (Selected) Improved Critical: Slash Weapons

Level 14 (Fighter)
Feat: (Fighter Bonus) Greater SWeapon Fighting
Level 15 (Rogue)
Feat: (Selected) Force of Personality
Level 18 (Bard)
Feat: (Selected) Empower Healing Spell
Few thoughts.
1.) Power attack and Precision cant be run at the same time (ditto with stawart def I think). I was running the enhancemnt to give +5 dmg with Precision. This is cause I did not think out everything and thought the to hit might help over the loss with power attack because I was going to weapon finesse and use Cha for Dmg. But ended up maxing str, so I think I'll trade out percision for cleave and Force of personality for Greater cleave, opening up overwhelming crit for epic.
Still trying to figure out Epic feats, but remember inspire excellence requires 15 bard levels, so that is not an option.
the Dmg with Swash and going into Kensi seems pretty good. I'm currently pretty heavy into WC tree as well, but the chants are underwhelming (6 dr is nice, but does not stack with much, so underutilized) although the rage is nice (its much longer 4+min then the tool tip says)
Also not sure the Empower healing is the best choice, but I really wanted this guy to heal decently. Might switch some points from WC to Spellsinger for stronger scrolls and longer songs.
Please let me know what you end up going with, I'm sure there is alot of room for improvement in my build.
