Itami - The Escort of Doom
Itami is a melee assassin. He leaps from enemy to enemy, and causes enemies to just beg for death.
Passive - Coup de grace - Itami's abilities and basic attacks critically strike enemies under 40% health.
Q - Winged Fury - Itami flushes out his wings, and dashes forward, knocking aside enemies he passes, dealing damage, and will stun any targets around him when he finishes. He can stop mid-dash, giving a reduced stun duration. Kills will refresh the ability.
W - Satan's Power - Itami's wings turn red, and all basic attacks for a duration deal bonus true damage.
E - Shadow's Call - Itami sacrifices 5% of his maximum health to deal 5-10% physical damage based on the targets maximum health.
R - From Under the Earth - Itami becomes invulnerable as he travels under the earth, on his next basic attack, he reappears, snapping the targets neck, and dealing 50% of the targets maximum health as true damage. This can be cast again but not on the same target.
When taking down solo targets, your basic combo should be:
Lead in with a fully charged Winged Fury, for the long stun, then, activate Satan's Power, and then use From Under the Earth, use Shadow's Call soon after, and finish them off with basic attacks, Coup de grace will assist in the finishing.
During a teamfight, your combo should be to take out the solo target (up there^^^) and then try to use that same combo to another target. Preferably the other carry.
