Ok that seems like a lot of skill points. You'll need to check with your friend to see if he wants any skill points added to jewelry. Because he will be stealthing, his armor needs to be leather or have the mage armor property. I also recommend 70s resist, lower mana cost 40% if possible, to help him with mana for special moves and ninjitsu spells. If you have room, maybe add hit chance increase and defense chance increase on the jewlery. Also if you have room, add stamina increase and some stamina regen. I find that I lose stamina a lot in llama form, so try to add a little to his suit. Finally, if you have the extra room, you can add +stats to his jewels or maybe hit point regen on his armor. If he's human, I recommend the nocturne earrings for night sight. He can't steal with anything in his hands, so having a shield would be kind of useless. Even when he's using the smuggler's edge, he can't use a shield. So don't count on adding a shield as part of his suit. Also, there are a variety of talismans which can help with properties, robes, aprons etc. He said he wanted a high end suit, so taking advantage of all of those things can really improve his suit. I'm brain dead after a bad day at work. If I think of something else, I'll come back and add it.
