It would be more of a grenadier build, tossing out potions and flasks and tanglefoot bags and so on to help debuff and damage the enemy during combat.  Though, having a Packmate homunculus to carry potions and a Dedicated Wright set up in a portable hole to help with crafting would probably both be good ideas.<br/><br/>Launch Item is a 0th-level Sorcerer/Wizard spell in the Spell Compendium, and a custom magic item that let's you use that spell at-will at CL 1 would cost 1,000 gp, according to the rules.  You'd be able to launch your various items up to 110 feet without suffering range penalties on your attack roll, and since you'd be attacking with splash weapons, they'd all be touch attacks, as well.<br/><br/>It would be a bit costly, but I think it would be fun to play. ^^
