Icarax by Meemaster

Whenever Icarax loses 1% of his maximum health, he gains 1 Wrath. For each Wrath he has, his attacks and abilities heal for 1% of the damage they deal. Icarax can hold up to 100 Wrath at once, and Wrath slowly decays if Icarax hasn't taken damage in the last 3 seconds, losing 1 Wrath per second.

Icarax fires a homing bolt towards every enemy Hero within a certain range of him. The bolts are destroyed upon hitting terrain or an enemy, but deal 76 damage if they hit an enemy Hero. If Icarax is at 50 or higher Wrath, the bolts also explode, dealing 50% damage to enemies caught in the explosion.
Icarax loses 5 Wrath for each bolt that doesn't deal damage and gains 5 Wrath for each one that does.

Icarax slams the ground, dealing 156 damage to nearby enemies.
Wrath Smash costs 15 Wrath, but Icarax gains 5 Wrath for each enemy Hero hit.

Icarax gains 5 Wrath for each nearby enemy Hero, then heals 1% of his missing health for each of his Wrath.

Icarax instantly gains 100 Wrath, and his attacks deal 3% additional damage for each of his Wrath for 8 seconds.
Afterwards, Icarax loses 1 Wrath per second until he has 1 for each 1% of his maximum health he currently has missing.

Icarax loses all of his Wrath and gains 4% of his maximum health as Shield for each Wrath lost. This Shield quickly decays over time.
