Backpack Battles builds, recipes and shop planning

Start from a class loadout and arrange your items around bags and stars. Use Crafting planner to check which ingredients you have, what is missing and which catalysts you keep.
Check Shop rarity odds by round before spending, then use Run budget to plan purchases and rerolls. Your unfinished backpack stays in this browser; save it to your account or share its link.

Guides
Cooldowns, buff ticks and fatigueA fight is not a single damage-per-second total. Items have individual activation rules and cooldowns, while shared combat events process other effects on their own schedule.
Recipes, catalysts and crafting choicesA crafting recipe has a base item, separate ingredient positions and one result. Two formulas for the same result are alternatives, not one combined shopping list.
Choosing a subclass in round 8Round 8 brings a choose-one offer containing all five subclass-defining items for your class. It also grants 10 additional gold.
