Try this mfing Well, i have a lvl 80 mf sorc and all she uses is full tals set. this will only work if you have no resistances in negatives, especially lightning or poison. anyway, the next time you are mfing at mephy you should try this. First tele down to the portal at durance lvl 3. cast a tp just in case you have some trouble. then walk right up to meph, standing so close that you can actually hit him with wutever weap u use (even with an occulus). Use static field on him a few times till his health is halfway there. then, use water skill u use to kill him. by standing right next to him, he will only hit with his hands, not using his killer baal of ice. you will most likely be poisoned, which is why u need SOME poison resistance. this works for me and i hope it does for you. go head and try it out and tell me what you think.
