Boss Guide

Diablo

History: The brother of Mephisto and Baal. He is the most versatile of the three. He can cast a multiple of spells, and his melee attack is very powerful [That’s why resist is essential]. He is found in the Chaos Sanctuary in Act 4.

Attacks:
Cold Touch [Diablo raises his hand to grasp unholy energies, then lays it upon on a target nearby, freezing and damaging it]
Lightning Inferno [Diablo shoots a stream of lightning in a sorceress Inferno style]
Flame Nova [Diablo raises his arms and a large ring of flames eminates from him]
Run [Diablo runs differently than he walks, and it gives him a major boost in speed]
Physical attack
Bone Prison [similar to the Necromancer's Bone Prison]
Firestorm [Like a Druid's firestorm attack, but actually deals real damage]

How his attacks work: Diablo's attacks can all be avoided in some way. His Lightning Inferno can be totally negated if you are right next to him. The bone prison can be teleported out of. All of his magical attacks are elemental, and won't do any damage when the sorceress has max resists. He is an easy boss, but summoning him by opening the seals is the hard part.

How to kill: Make sure you have the Act 4 River of Flame Waypoint. Before going in, make sure you have shiver armor casted. Clear out the Chaos sanctuary, then open the seals. The minions that pop up are much harder than Diablo himself, especially Lord De Seis who is Ice immune. Most sorceresses will not do Diablo because the minions are so damn tough. When Diablo is finally summoned, cast static field until he goes to half, teleport away, then orb him to death. Although its easy to just stand there and orb him to death, try to teleport away from his attacks so you don't have to buy potions.

Watch out for:
Flame Nova: Weak sorceresses can get destroyed by this, due to its range and damage. A sorceress must have high resist in order to face Diablo effectively.
