Build Lab¶
Select a character, weapon tier ids, repeated items/upgrades, level and trial wave. Evaluate the fixed build to see final stats, per-weapon expected DPS, contribution rows, active sets, tag counts and linked effects. Run repeated fixed-build trials for survival, kills, time alive and damage taken. Use the comparison/preset controls to keep two builds or save a regression build selection.
Contribution Amount is an effective delta. A Set can subtract an earlier fold; a Limit can reduce the result; efficiency and final rounding affect the sum. Source identifies the provider, while Input Source identifies a dependency such as currency. Custom-handler net contributions appear in the Store residual. Convert recipes do not spend resources during evaluation: completed gains appear as their generated ledger entries.
Expected weapon DPS and measured scenario DPS answer different questions. A weapon outside range, a moving target or a sparse crowd can produce a lower measured value. Use a whole-run simulation to include shopping decisions.
