Features

  • Full Loadout Planning: Fill all 6 weapon slots and 6 passive item slots exactly as you would in a run, with a level control on every slot
  • Character Bonuses: Pick any of the 25 characters — their starting weapon is placed automatically and their passive bonus feeds into the stat totals
  • Evolution Highlights: Matching weapon and passive slots are linked with a shared badge and turn green the moment the evolution is ready
  • Union Evolutions: Multi-weapon evolutions like Vandalier (Peachone + Ebony Wings) track every weapon they need, not just one
  • Evolution Checklist: A live panel lists each evolvable weapon in your build and tells you exactly what is missing — the passive, more weapon levels, or nothing at all
  • Stat Tracker: Compounding totals for Might, Area, Cooldown, Duration, Amount, Luck, Growth and more, recalculated as you change any slot or level
  • Duplicate Protection: Items already in the build are marked and cannot be picked twice
  • Shareable Builds: The URL updates as you build, so copying the link shares your exact layout — character, items and levels included
  • Text Summary: A plain-text version of the build for chat clients that strip links

How to Use

  1. Choose your character from the dropdown. Their starting weapon drops into the first slot and their bonus is applied to the stat tracker.
  2. Click an empty weapon slot, filter the list, and pick a weapon. Repeat until you have the six weapons you plan to run.
  3. Click an empty passive slot and add the power-ups you intend to collect.
  4. Use the − / + / max buttons on each slot to set the level you expect to reach. Evolutions require the weapon at max level.
  5. Watch the slot badges: a yellow badge means the weapon and passive are paired but the weapon still needs levels, green with a star means the evolution triggers at the next chest.
  6. Check the Evolutions panel for the exact requirement still outstanding on each weapon.
  7. Read the Stat Tracker to see how your passive choices compound — watch Cooldown and Amount in particular, since they drive damage output more than raw Might.
  8. Copy the share link to send the build to someone else, or the text summary for places where links are stripped.
