ENDLESS EXPEDITION
How deep
will you go?
One more floor. One more risk. A different kind of expedition beyond the southern road.
Find the entrance
From Willow Village, travel south to Cinderveil Approach, then south again to Descent Hollow →. The cave stands to the right of the southbound path. Choose any of the six difficulties and start at floor 1 with your current equipment and talents. You arrive in a safe room using a seeded regional dungeon layout. Use the east door to begin the first fight; its west door leads back to safety. The entrance has no extraction shrine and does not count as a cleared floor. Later floor advances lead directly into combat.
Floors and enemy waves
Clear every active and queued enemy before advancing. Floors contain 12 + difficulty’s extra enemies + 2 × (floor − 1) ordinary enemies, plus scheduled bosses. Enemies arrive in saved waves with at most 20 active or reserved enemies. Themes and encounters derive from the root seed and floor.
Enemy health grows by 1.08floor − 1 and damage by 1.04floor − 1, multiplied by the selected difficulty. Base resources grow by 2% per floor after floor 1. Depth does not speed up warnings or attack cadence.
The boss schedule
Every fourth floor schedules bosses. Every tenth floor schedules a raid encounter, including tenth floors that are not multiples of four. A scheduled floor has 1 + floor(floor ÷ 4) total bosses; every tenth floor includes floor(floor ÷ 10) raid bosses. Boss groups queue with up to four active boss slots.
Bank at checkpoints
Banking happens after cleared scheduled boss encounters. Loot collected since the previous bank remains at risk until the next checkpoint. There is no finite victory or normal dungeon completion prize. Suspend through the game menu to preserve a run; backgrounding pauses the game.
Depth equipment
A drop from floor N has a fixed multiplier of 1 + 0.025 × N. For example, a floor 20 copy has +50% weapon/spell damage and wearable health/defense. Weapons scale damage and granted spell damage. Wearables scale health and defense. Ranges, cooldowns, proc chances and wearable yo-yo bonuses do not gain Depth.
A stronger Depth drop can replace owned gear after confirmation. Accepting resets all purchased upgrades without a refund; declining converts the incoming drop to coins. The expedition retains the loadout snapshot it started with, so checkpoint inventory changes apply to future expeditions.
Depth copies are documented through their item family pages rather than generating a page for every possible floor. Explore the equipment catalog →
