HAHAHA omg siler i love you.
im about to let you into the secret of ubers.
but i have to open up D2 to get my account name i forgot it O.o
but as far as ubering goes, here goes my explanation....
First off its like one huge acid trip, the trick is to harness it and then figure out how to fend off the scary monsters.... HAHA im just kidding thats good though.. not...
Ok here it REALLY is.
once you open up the portal you should send someone in to LURE MEPHY FIRST, he is by far the hardest to beat because he brings all of your res' down to shit. and he is the reason for the fuckers that pop up around you (skeletons at least) they are not fun, then i would lure BAAL and take him out he isn't too hard, but it is always good to have the smiter go in first, and a zealer taking out the minions that come up. Lastly you go for DIABLO he is not too tough either, just if you mess up and lure any of the two WITH MEPHY you're fucked and you have to lure them away and make a shit ton of sacrifices of YOUR LIFE haha. but its actually quite simple, it just seems like it, i do ubers like its kandi... *PUN

its easier when you actually do it.
