Satanic

The Satanic is an Item purchasable at the Main Shop, under Artifacts. However, it can only be completed with items from the Secret Shop. It grants the most lifesteal of any item in the game. The more damage per second the owner does, the more HP he gains, making it particularly efficient with an Agility hero.

Additional information
One Satanic grants a total of 475 health, 0.75 health regeneration, 5 armor and 20 (45 for strength heroes) attack damage.

Tips

 * Satanic's active ability, Unholy Rage, has quite a short duration. If the enemy has many disables, it is recommended to get a Black King Bar first and use them together, or wait for the main disables to get used first and then join the fight.
 * Since lifesteal heals for the actual amount of damage dealt, attacking targets with low armor and damage reduction and/or obtaining high amounts of attack damage can greatly increase the survivability in a fight. With high enough attack damage, one critical strike during Unholy Rage can potentially fully restore the user's health.
 * Dominating a creep with Helm of the Dominator then purchasing Satanic will cause the dominated creep to die.
 * Missing an attack does not grant lifesteal. Consider a Monkey King Bar if an opponent has evasion.
