Assassin..

MY advice for this is to just get the weapons from the shop and kill what the guide told you. Upgrade your claws(like titan to mithril titan, gold if rich). Then make Meba and get +7. If your a bandit-thief then stay with the most up-to-date weapons(try to get above average if cheap). Another thing I would advise you to do is to upgrade the glove that you get from Nella's Quest (lvl 15) with an opal and some mesos. The upgraded gloves give you a LUK bonus and a +2 DEF bonus. Also, if you are a dexless sin, you should get a +7 Garnier and use it until lvl 35, and get a maple claw, then kandayo at lvl 43, and shinobi bracer at 50 (or was it 55?). Also, try to get a high dex sauna, unless you want godly damgae, for that get a 50 luk sauna.http://strategywiki.org/wiki/MapleStory/Thief_Guide/Equipment
