Data status: This page explains mechanics and decision rules. Where a precise number matters we say so and mark it, rather than guessing.

A harder ladder

Ascension is a set of modifiers you stack as you climb. Each run can carry a higher level than the last.

The changes touch the parts of the game you lean on. A small tweak can undo a familiar plan.

What shifts

Lower levels trim your starting edge, like less gold or weaker opening relics. You feel it early.

Higher levels add enemy strength and limit healing. The late game turns from hard to unforgiving.

Climb when ready

Treat each Ascension level as a new game. What won at level one may fail at level five.

Build cleaner decks and take fewer risks as you rise. The ladder rewards discipline over flair.

Next: Common mistakes.
