When to face Diablo?

[Bob the Beholder]

Well, sounds like I'll be ok, but I think I will level to 30 for venom and my shadow master.  Luckily, my lightning resis is ok now.  Question :  His red lightning, how much is fire damage, and how much is lightning damage?

Yeah, they really made meph harder, likely because people were running him.  He used to be a pushover.  To deal with his cold attack, you could always get half freeze duration, or the set belt (arctic binding I think it is) that has cannot be frozen, or another such item.  I was fortunate enough to find this belt, and found it really helped in Travincal in act 3.  The only bad thing about this belt is that you only get 3 rows of potions, not 4, but no biggie, you can always go to town and refill.

Yeah, once I get used to the animations of his attacks and how to avoid them, I should be ok.  Where do you hide in the chaos sanctuary without getting cornered?  Oh, and how do you find his drops to be since 1.10, better than before?  Do you get many sets/uniques?

From my own memory, the lightning breath is half physical, and half lightning. This was from back before the expansion, though, so it might have been changed since then.

And as to hiding, it's not so hard. The entrance area to the Chaos Sanctuary usually works. Just run there, quick. Diablo tends to have problems getting past the large lava-pits/walls/whatever they are, as the side passages that you can go through are pretty narrow.

The drops I'm not an authority on. I haven't gotten anything good from an uber-drop since about two months after Diablo II came out.
