Best Place For Getting ExperienceEdit
Boss dungeons will offer you the most experience points because of their multiple levels as well as the treasure chest of coins and experience after the boss is defeated. Ultimate Rampage is not ideal because enemies get progressively harder as well as tougher to kill, while dropping sparse amounts of experience points for your work.
Best Place For Getting GoldEdit
Ultimate Rampage is the most ideal as you progress through the floors, earning 500 as a starter. The trick is to try to run across the floor as fast as possible without attracting too many enemies. Also, avoid picking up "loose change" on the floor otherwise it will jeopardize your chances of progressing to the next floor.
