About this game

Start with nothing, become a legend — an idle dungeon RPG!

Explore endless dungeons automatically and grow your hero.
Your hero keeps fighting while you are away or asleep.

- AUTO BATTLE & IDLE GROWTH
Fully automatic combat, offline rewards and an ultra power-saving idle mode. Your gear is never lost on death — just climb again from the stage's first floor.

- SATISFYING LOOT
6 rarity tiers x quality system, Normal through Mythic. Your character's appearance and weapon effects actually change with your gear. Guaranteed boss drops, legendary pity system and no enhancement cap at the top tiers.

- GO DEEPER ON GEAR
* Refine — spend gold for a chance to push one option higher, up to double its normal cap.
* Reroll all values — option types stay, only the numbers are rolled again. Higher quality rolls higher.
* Inherit — pass hard-earned enhancement levels on to a new item. The cost is enhancement levels, not gold.
* Sets — collect all 6 pieces of a Lord's mythic set to complete its set bonus.

- TRANSFORM CARD COLLECTION
64 transform cards including 10 elemental Ancient dragons. Orb summon reveals with rank-up surprises, collection rewards and unique combat styles per card.

- CLASSES & SKILLS
Change among 23 classes to build your hero your way. Learn 24 skills from skill books (attack / AOE / support).

- WEEKLY RAID: JUDGMENT OF THE RIFT
A new world boss opens every week. The goal is not the kill but the damage — your best run of the week goes on the global board.

- HUNT: THE FOUR LORDS
Wolf King, Blood King, Heaven Demon and Dullahan. Each Lord fights its own way, so bringing the right build matters — every one of them must fall within 30 seconds. Each kill drops pieces of its exclusive set, and kills stack to unlock the next Lord.

- ARENA
Build your team and take on other players' defense teams. They don't have to be online, so you can challenge any time. Win to climb RP and rise from Bronze to Challenger.

- SWEEP
No need to re-fight a floor you have already cleared. Spend a sweep ticket to skip the time and take the rewards. Tickets refill daily.

- PLAY TOGETHER
Compete on the global stage ranking. 7-day check-in rewards and daily free gems. Korean & English supported.

- RETRO PIXEL ART
500+ monsters in classic pixel sprites across 5 themed dungeons (stone / cave / lava / ice / abyss).
