Lifestealer is a melee character. His primary attribute is strength. The hero is mainly taken as a carry in the easy lane.
Lifestealer is one of the few independent carry heroes. Thanks to the Feast ability, he shows a good performance on his lane, especially against strength heroes. When the character persues an opponent, Ghoul Frenzy will make it more difficult for an enemy to escape. Rage allows Lifestealer to survive almost any magical initiation coming from an enemy. Infest can also be useful in various situations from saving the hero or his ally to a sudden attack on an enemy. The ability can be upgraded with the purchase of Aghanim's Scepter, which will allow Lifestealer to safely deal damage to any opponent. Open Wounds is an activated ability that becomes available after the purchase of Aghanim's Shard. The spell can be alternately cast on nearby enemies making almost any team fight easier for Lifestealer's allies.
N'aix was a thief cursed by the Vile Council with longevity, so that its life-sentence for theft and cozening might be as punishing as possible. Years later, a careless spell cast by an imprisoned wizard woke up a terrible creature in N'aix. Giving himself up to madness, Lifestealer got out of the dungeon, and swore that no one would ever restrict his freedom again.
