The rule of four

Every room is a bargain.

Four cards hit the table. You face three. The untouched card becomes the Stray and follows you down.

I

Read the room

Monsters, remedies, and weapons arrive together. Order matters.

II

Bind the steel

Once a weapon kills, it may strike only a weaker foe. Every victory narrows the blade.

III

Keep the oath

Reach the end with Seal remaining and the oath holds. Lose it all and the Stair records the debt.

Steel and the Binding

The weapon remembers who fell.

A blade is not a permanent answer. Its last kill becomes its limit, and the next monster must be weaker. Bare hands are always waiting, but they take their price from your Seal.
