Endless Tower

Edition: Base Edition. The Endless Tower replaced the old dungeon system.

Starting a Tower run stops your repeating skill action. Fight monsters while the floor timer fills, then defeat its boss to ascend. Defeat restarts the current floor with restored HP. The Tower has no final floor.

The first floor’s monster phase lasts 2 min. Later floors scale that time by 1 + (floor − 1) × 0.015. Reference power is 10 × 1.075^(floor − 1). Monsters and bosses become stronger as you climb.

Your equipped combat gear contributes HP and power. Tower weapons, artifacts, and the robot add further bonuses. A monster kill restores 100% of maximum HP, capped at full health. Offline Tower progress is capped at 24 hours.

Reward Monster kill Boss kill Chest
Weapon rolls before artifact bonuses 16% chance of one One guaranteed 3–6 guaranteed
Robot part chance 0.6% 6% 15%
Artifact chance 0.15% 2.5% 5%

While active, a chest accumulates every 5 min, up to 5 held chests. Open them to make room for more. Boss weapon drops use the next floor’s power and receive an extra quality roll.

Tower weapons have their own stash of 5 slots. Higher-DPS drops automatically equip. Stash weapons you want to keep; the recent-drop list is limited. Weapon quality, condition, prefix, suffix, and drop floor determine its power and sale price.

Each weapon roll has a 1 in 500 chance of selecting a unique weapon. Unique weapons have no crafting potential. Other weapons receive potential according to quality.

Weapon Description
Law’s Retribution The weight of sin heavily draws this dagger to the ground.
Fate’s End You call out for mercy, but there is no answer.
Tyrfing Do not touch this cursed blade, for it only seeks death.
Surtr A red glow surrounds this blade, and it’s too hot to hold.
Excalibur The lady of the lake calls this blade’s name.
Zulfiqar There is no sword but the Zulfiqar, and no hero but Ali.
Gramr The bark of a tree still clings to the blade. Odin would be pleased.
Masamune Inscribed with the letters HONJO, it emits an eerie cry.

Craft stashed weapons while they have potential remaining. Rerolling a prefix or suffix costs Arcane Dust: 3 + floor(quality rank / 2). Each reroll consumes a random amount of potential.

An optional rune costs one extra item and multiplies the matching prefixes’ selection weights by 12; it does not guarantee a matching result.

Rune Favored prefixes
Fire Runes burning, blazing, smoldering
Water Runes cold, chilled, frozen, glacial
Earth Runes sturdy, solid, rigid
Air Runes quick, swift, focused, centered
Nature Runes keen, accurate, sharp
Lunar Runes holy, lightforged, fatal, deadly

Empowering consumes one Worldheart Gem, raises condition one step, and spends all remaining potential. A weapon must have potential remaining and be below the highest condition.
