Hydra

Hydra is one of the most profitable, soloable bosses in game, pulling in on average over 4.5 m gp/hr, easily one of the best money making methods in game. It’s actually a pretty easy boss to learn even compared to something like Vorkath. Hydra is basically Vorkath with the addition of valuable rare drops, you will easily make 3m gp/hr even without finding any uniques. Having a solid understanding of the hydra’s mechanics before you attempt him will make getting him down consistently a walk in the park.
