Dota 2/Abaddon the Lord of Avernus

Abaddon is a melee strength hero who can be played as a support or a semi-carry. His ability makes him a naturally durable hero. His spammable Mist Coil lets him repeatedly deal damage to his enemies or heal his teammates, provided that Abaddon has the health to support it. His Aphotic Shield is a useful protective spell that purges and absorbs damage, while being able to hurt enemies if it absorbs too much or lasts long enough. Abaddon's passive, Curse of Avernus places a debuff on enemies he attacks, buffing allies who do the same. Finally, Abaddon's ultimate, Borrowed Time, briefly turns all damage dealt at him into health, greatly increasing his tankiness.
