Zeroth: The Black Well
One sword. Thirty floors down.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Forged from a smith's own blood, the demon sword Zeroth has awoken. Thirty floors and ten bosses await. Awaken the blade, take a demon's form, and descend.
Zeroth the smith forged a sword from his own blood and life. With the last hammer stroke his breath stopped, and the sword awoke.
You arrive in Aren Village holding that sword. South of the village, monsters are crawling out of a bottomless old shaft called the Black Well.
■ ONE SWORD, ENDLESS GROWTH No other weapons. Only Zeroth. Earn points as you level up and awaken the nodes of the Sword Tree one by one. Dash, Whirlwind, Leap Slam, a summoned Sword Wraith — awakened skills link through chain nodes and flow like combos.
■ DEMON FORM Release the power within Zeroth and take on a demon's form. Damage, attack speed and move speed double. But hesitate without cutting an enemy, and the raging power strikes you as lightning.
■ 30 FLOORS, 10 BOSSES Every floor brings new terrain, monsters, treasure chests and elites. Floor bosses have their own patterns and won't fall to auto-hunting on the first try. Read them, dodge them, gear up and come back.
■ MAGIC STONES AND ARMOR Find magic stones with random stats in the dungeon and socket them into the Sword Tree. Craft each armor piece at the smithy from boss materials, then upgrade it up to +10.
■ VILLAGE LIFE Rest at the inn, shop for supplies and take on requests from the villagers. Help the pet keeper at the barn, and Cotton the rabbit will join you, fetching your loot.
■ THE ABYSSAL RIFT Defeat the boss of floor 10 and the Abyssal Rift opens. Three times a day, cut through the swarming monsters against the clock and gather materials to upgrade your armor.
■ PLAY YOUR WAY Fight by hand with a virtual joystick and skill slots, or tap AUTO and let the hunt run floor by floor.
