Kaus

Kaus is an NPC found in Dragontail. Upon talking to him, he requests that you train him for his fight with Rollim in the Mage Faction.

Upon defeating him, he can be fought again after 24 hours, getting progressively stronger until the final fight on your 7th day. After you defeat him at the 7th day, he gives you a Bag of Gold as a reward for training him. The Bag of Gold sells for to NPCs.
