Well first replace that belt with a t-gods. 90 light res and light absorb saves your *** against meph. If you are still dying before life tap triggers (it honestly should take seconds despite you only having a 5% chance to cast) I suggest buy a wand with life tap charges so you get a guaranteed cast.
Second, switch out that credendum ring for either bul's (for life), SOJ (for mana), or a Wisp Projector (light absorb if you don't want a t-gods belt).
Don't forget to BO, it is alway helpful.
And finally are you attacking them all at once, or leading them out one at a time? If you can survive all at once do so because that means you don't have to wait for life tap to trigger 3 times, as the first time it casts it will get all three of them.
Also what are your stats in str, dec, vit, and mana? What is your total life after BO and do you have max block?
The hardest part for me is getting uber izzy killed (I buy keys b/c they are cheaper) as I always get IM in the middle of zeal and 1 hit KO myself because of the insane damage done by grief.
Because my pally with a similar setup (go back a page or two) can solo the Ubers without leading them out, in an 8 person game. It takes awhile longer because of their higher life, but I still don't die.
I am actually very poor so i dont have a CTA atm, and i cant afford Soj or anything like it..
i am aiming to get a torch the whole time that i can trade for a ist or something like that, so i can get another UT try, some point i am getting a pala t with a high valuehehe.. then i get lots of Ists..
Got to come back to the problem, i think life tap is protting enough, its the problem to get life back from a target i gotta struck the target.. somehow i dont do enough dmg ? can that be ?
you just need more basic life to with stand couple of hits before leeching everything back. ask friendly barb to give bo, or dual log to bo your self. much cheaper then cta and higher bo. ( 2 sticks, 1 amulet boosts your bo to level 30 already ( with BC ) )
how would he or anyone dual log? or are you talking about 2 different pcs?
