Wraith King

Ostarion the Wraith King is a melee strength hero, a carry and tank capable of both dealing and taking plenty of damage. His infamous Reincarnation allows the Wraith King to rise again after death, acting like an Aegis of the Immortal, making him especially difficult to kill. But if left alive, the Wraith King can wreak havoc upon his enemies; his Wraithfire Blast provides reliable damage and a stun on a short cooldown, Vampiric Aura grants his team sizeable lifesteal, and Mortal Strike helps make short work of foes.

Tips

 * Wraithfire Blast is a very good nuke, allowing you to disable and slow at the same time. A perfect tool for ganks and team fights, it has a relatively low cooldown, but your small mana pool won't allow you to use it frequently. Save it for when you really need it.
 * It's generally best to have Wraithfire Blast maxed first as Ostarion's passives aren't very good in the laning stage.
 * Learning Vampiric Aura during laning phase will shift the creeps equilibrium and you'll be forced to farm and fight closer to the enemy tower, which will make you more susceptible to enemy ganks in the early game.
 * Always make sure to save some mana for Reincarnation, since it will not activate if you have less than 140 mana.
 * One possible solution to this problem is to have a Soul Ring, since it will grant you 150 mana at the cost of 150 HP, this will usually guarantee Reincarnation activating unless the enemies have mana burning capabilities. Vampiric Aura can allow you to regain HP lost by Soul Ring.
 * Try to initiate and tank as much damage as possible in team fights. If you are the last to die, nobody will be able to help you when you activate Reincarnation!
 * Refresher Orb is highly situational, as it allows you to potentially Reincarnate twice in a fight allowing you to deal damage for a longer period of time.
 * Picking up the Aegis after killing Roshan is an excellent idea. It essentially gives you 3 lives, though Reincarnation will activate first as long as you have 140 mana. If you don't have the mana to activate Reincarnation, Aegis will activate first instead.
 * A Force Staff can help make up for Wraith King's lack of mobility, and it allows him to jump closer to his targets to make up for the short range of Wraithfire Blast.

Trivia

 * Before the Wraith Night patch, Wraith King was previously known as . His name and model were most likely changed to avoid copyright issues with Blizzard, since Blizzard will be including their very own Skeleton King (King Leoric) in their own standalone ARTS, Heroes of The Storm. Ostarion's transformation to Wraith King became tied to a commemorative event, Frostivus 2013, better known as Wraith Night.
 * This change may also have been made to better adhere to certain countries' censorship laws, namely the Chinese client.
 * His DotA incarnation was heavily based on King Leoric, better known as the Skeleton King. Leoric was a recurring boss in the Diablo franchise, another game made by Blizzard. He was an iconic boss in Diablo, and he reprises his role in Diablo III.
 * Interestingly enough, even though the change was made to avoid copyright issues with Blizzard, his incarnation as Wraith King resembles Leoric, from Diablo III, much more closely than his previous one as Skeleton King, especially his colour palette.
 * His responses to acquiring both the Divine Rapier and Armlet are a reference to a popular hero guide called "CAPS LOCK LEORIC".
