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.

Gameplay
Wraith King is a durable core with a reliable stun. As his ultimate, Reincarnation, effectively doubles his health in a teamfight, he is commonly built as a tank carry. He is traditionally popular among new players for his survivability and potentially simple playstyle. However, Wraith King can also be played at a high level of skill, particularly by using active items. For example, well-timed Tread switching can make his expensive stun much cheaper in the early game.

Tips

 * 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 maxed first as Ostarion's passives aren't very good in the laning stage.
 * Learning 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, since it will not activate if you have less than 160 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. 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 !
 * is highly situational, as it allows you to potentially 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 160 mana. If you don't have the mana to activate Reincarnation, Aegis will activate first instead.
 * A Blink Dagger 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.
 * A Mjollnir is often a good item because Wraith is usually counter picked by illusions and mana burn, the lightning are very effective against them. But also because Wraith King initiate he will return damages with static charges.
 * The main weakness of Wraith King is his movement speed, as he struggles against ranged heroes. You can fix this problem by going Mask of Madness and Blade Mail, the damages returned will be amplified. Get a Sange and Yasha to run at haste speed and get more HP to return.
 * A linken's sphere can be a good pick, it will protect you while fighting or escaping after reincarnation, gives you more HP and Mana pool.
