Gluttony

A rare hero whose damage scales off his HP. When he kills anything his Max HP increases up to a max of 30%, incidentally also increasing his damage. His Auto-Ult allows him to kill a non-elite or non-boss enemy in range by devouring them, which also recovers his HP, but against elite and boss enemies he deals a sizable burst instead. His Awakenings all add to his kit making him dangerous to be near for smaller enemies and his ult can make him useful for some situations.
