Aegis of the Immortal

The Aegis of the Immortal is a rare Item that drops from Roshan.

Though difficult to acquire, it can easily sway any battle, bringing back the carrier with full life and mana.

Additional Information
Killing Roshan will cause him to drop the Aegis. When the carrier is killed, they are brought back once with full health and mana at the spot where they died. The effect is announced by an audio cue and a gravestone over the dead Hero, followed by a short delay before their resurrection. Remember: a Hero revived with the Aegis will have full health and mana, but will not reset any cooldowns.

The Aegis is removed after its carrier dies or if Roshan respawns, 10 minutes after his death.

Reincarnation
Brings you back to life with full health and mana 5 seconds after you died, at the location where you died. The Aegis of the Immortal is removed from your inventory after reincarnating you once. Aegis of the Immortal is also removed from your inventory when Roshan respawns (10 minutes after he was killed.)

Trivia

 * Aegis was previously an ordinary recipe item that contained three charges. After it was removed, it was then given as a droppable item from Roshan.
