Each floor has progress that fills over time while you fight through monsters. A secondary bar tracks the current enemy’s health, worn down by your weapon.
Reaching 100% floor progress summons a boss with much higher health. Beat it to ascend a floor - lose and the floor’s progress resets.
Every floor rolls a random set of modifiers (Burning, Frozen, Cursed, and others). A weapon’s prefix can counter a modifier’s penalty and turn it into a small bonus.
Monsters hit back while you fight them, and defeating one heals a portion of your health, so gear quality directly affects how well you hold up over a floor.
Reroll a stashed weapon’s prefix, base, suffix, and rarity using Arcane Dust. Add a rune to bias the reroll toward a matching prefix family (for example, a Fire rune favors Burning or Blazing prefixes).
Each weapon has a limited Potential that is consumed (a random amount, capped at a quarter of its total) on each reroll. Once exhausted, the weapon can no longer be rerolled.
Legendary Worldheart Gems raise a weapon’s condition by one tier at the cost of all remaining Potential.
