Rules & references

Uses the site’s current S18 data and non-unique traits. Each champion counts once. Only one Lux form is allowed; her origin counts twice. Rival activates with exactly one champion, assuming no Rival augment. The hidden Eclipse effect adds no separate trait.

Enter actual team capacity, including extra slots from items. This searches trait combinations, not combat strength or win rate. Parentheses show the reached breakpoint.
