Demented Boa

"Wearing this shawl fills you with unforgivable rage. You feel no remorse for anything you've ever or will kill."

The Demented Boa is an accessory that can be found in the Underworld in Shadow Chests. When worn, it grants the player 30% increased melee damage, 35% increased melee knockback, 15% increased movement speed, and spawns an Imp to fight for you.
