Lifestealer

N'aix the Lifestealer is a vicious melee Strength hero whose abilities give him the power to bring down durable heroes quickly, while sustaining his health from absorbing the very life of his enemies.

The main role of the Lifestealer is to fulfill the job as a formidable carry, able to restore his life thanks to his skills. Feast is his passive ability and his signature, every attack he lands deals extra physical damage and consumes the flesh and blood of his victim, regenerating his health. With Feast, he can munch down tough and strong tanks. N'aix can send himself into a bloody Rage, increasing his attack speed and a short period of magic immunity. Open Wounds tears the enemy, causing the prey's wounds to open, bleeding their life essence, allowing him and his allies to feast down as well as greatly slowing them to a crawl. Rage and Open Wounds allows the Lifestealer to brutally rip his victim apart, feasting on their health in the process. When in need, N'aix can use Infest to hide himself inside of his allies or any non-hero units, laying dormant, until he is ready to come out, devouring the flesh from the inside, killing the non-hero unit, and bursting out the chunks of flesh and bones of his unfortunate host, damaging his foes around him, and ambushing them with carnivorous savagery. The Lifestealer is a monstrous beast of gluttony and greed, bent on stealing the lives of every living creature he encounters, violently killing them to sate the Lifestealer's terrifying thirst and hunger.

Tips

 * There is a term called the N'aix bomb among players which includes a N'aix player infesting a high mobility hero such as Storm Spirit, Puck, or Queen of Pain etc. to initiate upon enemies by having these heroes enter the fray and unleashing all of their own skills in quick succession before N'aix himself comes out of them and dealing the nuke damage of Infest while following it up with his dps using Rage.
 * Heart of Tarrasque is a good item pickup as it will allow Lifestealer to keep Armlet of Mordiggian activated indefinitely, and gives him greater durability.

Trivia

 * Lifestealer's fun/alternate name in DotA was Gollum, a significant character in the Lord of the Rings book series.
 * The old version of Lifestealer was a Strength hero with an incredibly high Agility potential (+4.5), much more than almost all the Agility hero themselves. Despite being a Strength hero, he had poor overall Strength. His old skills were:
 * Feast used to be an aura-based lifesteal which stacks with lifesteal attack modifiers. Unlike the Skeleton King's Vampiric Aura, Feast only applies to himself. The high life gain and high Agility makes N'aix a vicious warrior of great survivability, able to take down the old mighty Roshan.
 * Poison Sting acts almost similar to Venomancer's Poison Sting, but the slow is more potent, and it's an attack modifier.
 * Anabolic Frenzy was also a passive ability that gave some attack and movement speed.
 * Rage used to be his ultimate, with a longer duration, but it increases attack damage instead of attack speed. Rage makes N'aix an already strong fighter more fearful and dangerous.
