Insanitarius

In the deep jungles, a degenerate race is said to have worshipped the Hellbourne with exotic and unnatural rites. The only evidence of this cult are Insanitarius masks. Donning one bestows immediate battle rag--increased strength and Attack Speed, the ability to shrug off minor wounds, and rapid recovery from injuries. And by whispering a secret phrase, the wearer can invoke truly Insane Strength.
