Azmodan's first ability is...
Globe of Annihilation is an artillery shot, fiery meteor that deals impact damage to a very large area.
This ability is excellent for besieging enemy fortifications and keeping good distance from pesky rodent enemies.

Level 1
Taste for Blood
My enemies will not stand for this! Heh, pun intended. The longer they stale my victory, the more powerful I become.

Sieging Wrath
Well placed fiery meteors will devastate my enemy fortifications early on.

Master of Destruction
Tychus is ****ting himself. While commanding servant allies to fight alongside my minions, I may freely decimate entire enemy fortifications in less time than it takes to summon the Army of Hell.

Level 20
Perishing Flame
My minions have outlived their usefulness... BOOM! Strong in pushing a lane, during a split push (while all enemies are distracted by my servant allies).

Fifth Circle
My enemies shall cower before me!

Bolt of the Storm
If my enemies are formidable and I must be quick about my business, my safety is assured.

Forced Recruitment
My Generals of Hell will command the battlefield.
