Undying abilities

Decay

Undying steals strength from all enemy heroes in an area, dealing base damage as he claims the enemy's strength for himself. Deals 2x damage to creeps.

Aghanim's Scepter: Increases strength steal.

Soul Rip

Undying rips health away from all nearby units and uses it to heal an ally, or damage an enemy. Soul Rip can also be used to heal Tombstone.

Tombstone

Summons a tombstone at the target point. Zombies will frequently spawn next to every enemy unit in the area around the Tombstone, and attack them. Zombies have the Deathlust ability, which causes their attacks to slow the target, and if the target reaches below a certain amount of health, increases the attack and movement speed of the zombie.

Aghanim's Shard: Tombstone can be cast on an allied hero to bunker inside of the tombstone. Heroes that enter the Tombstone cannot leave for 2 seconds nor can they re-enter after leaving. If the tombstone is destroyed with a hero inside, that hero gets stunned for 2 seconds.

Ceaseless Dirge

When Undying dies he will instantly respawn in the fountain. Begins the game on cooldown. Cannot be refreshed.

Flesh Golem

Undying transforms into a horrifying flesh golem. While in this state, he gains a percentage increase to strength, bonus movement speed, and causes attacks to slow, apply damage amplification, and spawn Tombstone zombies.

Shambling into battle, Undying forces enemies to decide whether to flee his wrath or be torn apart by it. He drains strength from his foes, and summons a horde of clawing undead. When he finally becomes a hulking flesh golem, his enemies may already be overwhelmed.
