I will gladly take on the task of explaining ANYTHING that you might have questions about, Atrocity - and thanks for being so understanding! I think we're going to have a hell of a good time.
So, let's see . . . . we should have . . .
Strat's Bloodstorm Blade - what the final version will look like, of course, will be up to him . . .
dman's Healbot - sounds like he'll be able to do what he needs to in order to get the trick working, now!
My Ninja - full scouting, combat backup, and maybe even some healing, methinks (yay for Crusader!).
Dan2 - fear-based Barb - izzat right?
XXXX's Crasher - who was going to play this, again?
I think 5 should do it. I'll invest in Knowledge Arcana so we can buy ourselves an Artificer's Monocle to ID stuff with (I think that'll work).
OOOOOH! The Thri in Shining South should TOTALLY be the one you use, then, if you're going for the jumping multiweapon fighting boomerang-chucker. I like the Orc too, though - totally your call!
Without Proto, you may want to consider throwing Feral onto the Orc - he'd get pounce and fast healing, which would be slick as hell.
Your big issue with either build is going to be making sure your bonus to hit is high enough. Otherwise, you'll be golden!
