Pretty impressive how it still manages to progress even past magma core+ without a single forge on the way. The only source of haste is an armour, no rage generation, no damage scaling except the initial boost with the ring and at least damage doesn't decay because I've finally found rare shield around floor 14 (using legendary before :D). Queen cleaver appeared approx. the same floor as the shield:)
P.S. Wouldn't be possible without whetstones, saved my run pretty much.
