Low level, low complexity dungeons are easy to do, but the difficulty level of the dungeons quickly increases, with tougher monsters, and harder puzzles as you progress. The experience you gain for completing a dungeon depends on the level of the dungeon, the complexity of it, and several other factors, including how often you died. So, it's a good idea to have a strong plan if you want to maximise your experience gains and the number of tokens you earn. Bind a weapon so that you can take it with you from floor to floor. If you can bind more than one item, bind some armour too.
