Apotheosis Blade

The Apotheosis Blade is a powerful weapon in the lore of Dota 2.

Description
This Apotheosis Blade is the flaming sword of Lucifer himself, forged out of steel. As its name suggests, this wicked blade was forged to fulfill a single purpose: to allow the wielder to kill a god and assume their power. It is wreathed in the same fires that were used to brand Lucifer's wings six and sixty-six times until they were reduced to smoking stumps.

Heroes

 * Lucifer inflicts ghastly and lethal wounds with the Apotheosis Blade, simultaneously burning and slicing them.  It is so hot that his victims are cauterized by its blows.
 * The flames of Doom's sword depend on his current state. When he grows stronger, its fire flares up. But when he dies, it loses its flame, becoming a cold piece of steel.
 * The Apotheosis Blade may have been made out of his envy and defiance against the gods themselves.
 * Since it is now safely kept in the Burnt Hall of Weeping Rose, it's implied that the sword was taken from him in an unknown event.
