Charon is the boss of the Zombie Dungeon just north of Detlas. Once you slay him, you complete the dungeon and get awarded emeralds that fall from the top of the Zombie Dungeon's Tree. He is Level 38.
Defense
Charon has a large attack damage unless your thoroughly prepared, and can easily mulch through Level 30's and below. He has a high speed, and if you head to the western side of the cave of Charon, his minions spawn. They are Level 25 Dungeon Zombie's and they are relatively weak if you come with the right gear. A team of lower leveled players is recommended, however higher leveled players can easily solo the dungeon (Level 40+), just make sure you're packing a good weapon!
