Each phase lists what to buy since the previous one; the % on a card is how much of the build's score you lose without it. Lit pips under an ability are its upgrade tiers (green: new in this phase). Hover anything for details.

How builds are chosen

For each net worth, the optimiser searches items and ability upgrades that maximise the score: damage per second against the reference enemy × effective health^weight, averaged over short, standard and long fights, each both fresh and mid-match (long cooldowns still recovering from the previous fight). Each checkpoint starts from the previous one's items, so the builds read as a path.

Gun, spirit and hybrid differ only in where the offensive souls go. The fight assumptions (accuracy, distance, the target…) are on the Data page and adjustable in the simulator.

Partly simulated

• Each detonation deals its weapon damage (as bullet damage) at the fuse times; T3 makes the last one the big detonation.

• The slow is not scored; conditional weapon-damage items (Close Quarters, Long Range…) don't apply to it.

Values are base values with their scaling; the simulator shows them at a chosen net worth and build.

Value by net worth

Boons come with net worth; gun DPS is every bullet hitting at close range, no headshots. Items and investment bonuses come on top (see builds).

Souls spent in a category (each owned item's full price) unlock the highest tier reached. The biggest step is at 4.8k; after it each tier adds less per soul (weapon: +17.5% per 1k souls up to it, +5% per 1k to the next), so piling souls into one category has diminishing returns. Builds and tier lists include it.
