I've got the rest of the party more or less figured out (well, actually, I have six characters designed and depending on a few factors (one of them, not sure which yet, is destined to be my next PC) will use four of them + this guy, but still).
They are:
Pouncing TWF Skirmish Crit-Fisher (Barb/Swift Hunter/Warblade/Bloodclaw Master)
Teleport Full Attacking Shadow Monster (Swordsage/Teflammar Shadowlord)
Cannonball Chucking Pirate (Scout/Master Thrower/Bloodstorm Blade)
Canny Melee Specialist (Swashbuckler/Warblade)
Undead Hunting Sniper Assassin (Soulknife/Illumine Soul/Soulbow)
Courage Inspiring Violinist (Bardsader)
The final party will be four of those + the Occult Slayer type.
