Bossing is an enjoyable activity for those seeking an adrenalin rush. Most players will go bossing for the extremely expensive loot that they can receive. These bosses are the best for gamers looking to make a huge profit.  The Nightmare of Ashihama: This is a newer boss, which means the items are super expensive at the moment. The most expensive drop is the Harmonised Orb, worth over 850 million GP. The Inquisitor's armor pieces are selling more than +100 million GP, making this boss the most profitable.  The Theatre of Blood: Completing raids with a party of 4 can increase kills per hour and the chance to obtain legendary loot. The Scythe of Vitur is the best drop here and can be sold for 600 million GP.  Alchemical Hydra: The Alchemical Hydra is located on the lowest level of Mount Karuulm. The boss can be killed around 25 times per hour with a decent setup. The drops can range from 100k-50m GP, which makes the hydra extremely profitable to kill.
