Dota 2/Ostarion the Wraith King

Skeleton King is a melee Strength hero that is considered one of the simpler characters in the game, with only one active ability. However, he is still a very solid and fun hard carry, and one that is very difficult to kill. His Vampiric Aura and Reincarnation abilities gives Skeleton King amazing survivability, and his Hellfire Blast and Critical Strike lets him disable and rack up the damage. Skeleton King might look like the easiest hero to play in the game, but he can also be one of the toughest.

Hellfire Blast
Hellfire Blast is Skeleton King's only active ability. He fires a ball of hellfire that stuns the targeted unit on hit, then slows them and deals damage over time. Use this to initiate a kill, slow down pursuing enemies as well as disabling key heroes. You can also use it for harssment but the mana cost will be too high during the early game for it to be very useful.
