MYSTICCAVE [LVL110+]
At the request of the community, the administration decided to listen and added a new map with the strongest demons in the game, for easier EXP.
The tutorial is basic:
Get a HealthWine that drops from BloodyBat or RedDevil.
Be over level 110 and deliver it to the NPC Alcoholist in Mystic Castle (674, 340).
He will teleport you to MysticCave where you will find the monsters that give the most EXP in the game.
Happy leveling!
