masterwork chain shirt (250 gp)
masterwork thieves' tools (100 gp)
4 oils of keen edge (3,000 gp)
275 gp left over to buy pants or hookers or something
At least 3 attacks per round (up to 7 if he's under attack), decent damage output and low AC and hp. Damage output goes way the hell up and the bottom falls out of AC when using Shock Trooper. Being a sneaky type he should be able to use one of his oils before he initiates combat.
Is pouncing at +20/+20/+15 (2d4+49 15-20/x2) with AC 8 and 65 hp glass cannony enough? AC 4 if he wants to hit back any time he's hit.
