Tactics for Diablo (spoilers, obv.)

[kandrathe]

I cannot say how it is for the Barbarian, but the Monk has a couple of easy ways to deal with the Lightning.

Same. It's just one rather clearly telegraphed attack, no class should have a problem reacting to it. A single +armor Leap will take care of it, for example*. Now, if Sheablo (thehehehehe, sorry...) was also Jailor/Nightmarish/Frozen, things might look differently, but as has been stated: elites > D.

take care
Tarabulus

*at least up until Hell, no idea about Inferno.

With my Barb, I try to fight near one health well, until I use it, then move to the other one. I make Diablo come to me and either leap or charge to avoid his spell casts. This gives me time for my specials to cooldown. But, I'll hit him as I can until I can use the specials again. I tend to get caught in the cages though, so I save my potions for those occasions. For Normal, I just let the Ancients kill him. For nightmare, I used earthquake and wrath of the berserker together. In the Phase II, I just killed the shadow, then stayed out of the fire.
