Backpack Battles Database

Mechanics

Combat, shop rules and backpack interactions.

Runs and rounds

A run ends at 10 wins or after 5 lost battles. From round 2, each round pays gold and adds maximum health.

Shop odds

Every shop slot rolls its rarity from that round's own table.

Crafting

Bonded ingredients fuse into their result when you return to the shop after a battle.

Stars and adjacency

Each item has its own star pattern; its description says what can be affected.

Combat

Stacks resolve once a second: regeneration heals on even ticks, poison bites on odd ones.
