Gaetan3, you can still use those stats, but you can completly forget about Fire Trap. Get a shield with Alice, a nice armor and you can go ET as a debuffer. The Masquerades won't work on the MVP's anymore, but Slightness Mind has a debuff that makes the mob takes 20% more damage for 10 sec and work on boss-type monsters also. Now, if you want to try something different you can try with a hybrid build or a ASS build. They hybrid works fairly well against bosses, but the ASS will be a bit difficult for you. As in soloing the Endless Tower, I haven't seem a Shadow Chaser do it yet, but hey, there's always a first time, right?!
