How a run works

A run is a short string of doors. You see what is behind each one, then pick.

1Build your strength

Pick a door, then take a charm or a card.

A fight doorA group door with three fire wispsA mystery doorThe rest site door
Elite defeated: claim one of two charmsTake a card: four new cards to choose from

2Play your cards

Chain cards in one turn to hit hard.

A sea fight: two Bilge Eels and an Anchor Chain attack, with a hand of frost cards

3Fight a boss

Every path ends at a gatekeeper.

The boss Diabase attacks; you hold Guard and two buffs, he is bleeding

4Win the run

The Gatekeepers

Twelve bosses stand at the bottom of the Descents. Each one is a door that learned to fight back.

Ten decks, each with its own engine

Five decks from your first run, four more to unlock by playing, and Verge opens with a Diamond Key. Pick one at the door; it leans every reward that follows.

A door can hold up to four monsters. Aim each card at the one you want, or hit them all at once.

Go below the bottom

Beat Descent V, tap Go Deeper, and five more Descents open below: VI to X. Each trip in costs 3 Diamond Keys and pays a huge haul of golden Keys.
