(Estuary) Acheron, Underworld Guard

A random boss which appears after finishing off either a friend/guild memebers boss, or your own boss. Has 500,000 health. Given 20 minutes to defeat. This boss is different from others, as players seem to deal around double the damage they normally would (this is in comparision to (Cypress) Payne, Underworld Captian, on the first attack).
