CHOOSE YOUR CLASS

• Warrior — Max HP +50, Speed -15%. Brawl through anything.
• Mage — Damage +40%. Fragile but deadly.

BUILD YOUR RUN

Every enemy kill drops XP. Level up to choose from three upgrades — Common, Uncommon, or Rare. Stack damage multipliers, pierce through multiple enemies, add ricochets, go explosive, or heal on every dash.

Weapons drop from elite kills. The Rifle hits twice as hard at long range. The Shotgun fires six pellets and clears rooms at close range. Cycle weapons with the scroll wheel mid-fight.

Relics found on each floor give permanent bonuses for the rest of the run:

• Vampire Ring — +3 HP per kill
• Iron Boots — Reduce all incoming damage by 4, dash faster
• Lethal Arrows — Build kill charges; next shot deals +25% per charge (max ×5)
• Crystal Heart — +20 HP on pickup, regenerate 1 HP per second

Active Abilities unlock from upgrades: Fireball, Ground Slam, Smoke Bomb.

THE DUNGEON

Floors are filled with eight distinct enemy types — from darting Goblins and spread-firing Orcs to Bombers that explode on death and HealerImps that restore their allies. Every 5th floor, the Dungeon Lord appears: a two-phase boss that enrages below 50% HP.

Smash open chests for loot. Shoot oil barrels to create fire hazards. Break cracked walls to uncover hidden secret rooms with enriched rewards. Visit the shop between floors to spend gold.

META PROGRESSION

Gold carries over between runs. Spend it on permanent upgrades that give you a head start on every future attempt — starting HP, fire rate, pierce, life steal, explosive shots, and more.
