So with only 1 pt in SM, she's not much of a tank, and should get regularly slaughtered in Hell (even at slvl9). How do you keep from getting swarmed by the LIs? And have you taken on Hell Ancients yet?
I am surprized at how low a level your fireblast is for a lightning trapper fireblast is the "creme del a creme". having 20 in Dsentry and 15 in fireblast is a bit backwards but can be fun anyway. The 1 in shadow master works well since she is mainly a meatshield. Which merc are you employing I hope its something other than a Holy freeze or cold merc shattered corpses don't help a build based on Dsentry, (made that mistake a few times myself).
As for the ancients as long as you can stay clear of them the 1-5k+ lightning sentry will do the trick. start off by placing 5 of them out from the triangle that way the first casting will hit multiple ancients it helps to get that first hit then you can use static and lightning as well as mindblast to kill them. turn off your Dsentry and have your fireblast ready since there will be no corpses to take advantage of. Its a tough fight but a trapper can make it as long as they can avoid being in melee.
@AE There are atleast 6 types of trapper ranging from Lightning to Dsentry/Bladefury and each of them has a pure trapper build to accompany it. Try getting to Hell with a pure fire trapper and you'll understand how hard playing such a build can be. Especially without having a shadow. 1 point in shadow does alot for surviviblity.
Yeah, cloak of shadows alone is more than enough to keep an assassin safe. Especially non-melee versions. I don't really remember why I had a shadow on my ribcrackersin. Maybe because I thought it was stylish or because I didn't need any other skills. ^_^
As for fireblast... I found that getting just 2 more points in fireblast for one extra shot is already enough. Traps are so easy to put up and after 5 shots my traps run out of targets anyway.
