Boss

Diabase

Diabase portrait

The floor of the Atlas, awake. It opens by dropping out from under you, and then it simply will not stay broken: it pours new stone into every crack you open and unmakes its own wounds while the grit it ground into you keeps working. You are not racing its damage. You are racing its repairs.

Boss 158 HP hits for up to 22 3.1 damage per turn on average

The floor itself, awake. It drops out from under you once, hard, and after that it simply refuses to stay broken: it walls the crack, unmakes its own wounds, and lets the Ember it ground into you do the killing. The only boss you beat by out-racing its repairs rather than its damage.

Tuned against

This boss is built to punish the Flame deck. It never stands at the end of Descent I against that deck; from Descent II on, bring something else, or bring an answer.
