Wave leak
Upgrade or replace the role that fails before spending on shiny goals or broad rerolls.
Advanced play is controlled testing: change one variable at a time, then compare wave leaks, boss pressure, upgrade timing, and reward targets.
Before changing your squad, name the bottleneck: wave clear, boss pressure, trait fit, evolution material, farming consistency, or pass value.
Upgrade or replace the role that fails before spending on shiny goals or broad rerolls.
Add focused damage, control, or an evolved role only after the wave route is stable.
Reroll only when the trait does not support the unit's current job.
Farm the material or currency that unlocks the next useful upgrade, not the rarest-looking reward.
Use summon-cost and AFK value only if those loops fit your session.
Treat speed as repeat-run value after you already have a consistent clear route.
Use shiny-rate value only if shiny collection is already your main goal.
After an update, run the same stage with the same upgrade plan before trusting old tier advice.
Use controlled tests: change one unit, trait, evolution, farm target, or pass-related loop at a time.
Run the same stage with the same upgrade budget and compare leaks, boss time, and whether the unit solves the bottleneck.
Evolve when it solves a current progression wall or anchors a role you already use.
Only if shiny collection is the current goal; progression players should solve wave, boss, and material walls first.
Because hidden rates and full stat tables can drift fast. Test what helps your current lane instead of trusting made-up numbers.
