yeah, using that exploit I've gotten to like the 25th floor now with no signs of stopping. Level 49 Draconian fighter w/ 67 str, 68 sta, 70 will, 68 int, 1.1M mana pearls and 5 armors equipped (including one in the weapon slot). I'm thinking this is uncharted territory since the enemies have stopped changing, but they scale up with each floor. Swarm and massive swarm and pretty much every offensive spell but critical strike are useless because the enemies have outpaced them.
There's a bug. If you drag from an equipped item to any other form of armor, you can equip anything in that slot. You could wear a sword like a helmet, or shoes
