Here's what I came up with: http://nwn2db.com/build/?239436
The xp penalty *cringe* aside... 25 perform curse song, Epic Rage w/Ice troll, can monkey grip a bigger weapon, inspirations, 26 STR, improved knockdown... what would make this better? (I'm on the fence about thundering rage)
PS. This toon may or may not ever see the light of day, so have fun shredding/fixing it.
