Unlock rules

A pending card or relic unlock postpones a character unlock. Daily victories skip character unlocks; losses in daily or custom runs can still unlock a character while a reward is pending.

A score award advances at most 1 unlock. The previous cost is subtracted and the remainder carries over. Above the next cost, the remainder is capped one point below it. An exact match is retained.

Ascension →

One victory with a character opens Ascension 1.

At your highest available level, a victory or reaching Act 4 in a standard run opens the next level, up to 20.

A seeded victory can save the next level. Custom runs do not advance Ascension.

Keys 3

Win a standard, unseeded run with each of these characters to make keys available. Daily and custom runs are excluded, unless a custom run enables the final act.

Recall

Obtain the Ruby Key.

Take the key instead of another rest-site action.

Emerald Key

Defeat the marked elite. You keep its relic reward.

Sapphire Key

Choose the key instead of the linked chest relic. Boss chests do not offer this key.

In Endless mode, Mimic Infestation suppresses the emerald key. The elite must also have rewards to offer. Mimic Infestation →

All 3 keys open the final act.
