If green Leona is attacking yellow Sett, does yellow Sett still get his passive Might bonus even after Leona's -8 Might debuff? Whose passive has priority?

Ruling: Both passives are calculated together simultaneously. There is no priority - all passive effects, buffs, and debuffs are added together in a single calculation.

Sequence:

• All passive effects are always active and calculated together
• Base stats + all buffs + all debuffs = final stat
• Example: Sett at 5 Might + 2 Might from passive + (-8 to minimum 1) from Leona = 1 Might final
• If Sett gains additional buffs that bring him above the debuff threshold, he can exceed 1 Might (e.g., 5 + 5 - 8 = 2)

Nuances:

• The "to a minimum of 1" clause in Leona's effect doesn't prevent subsequent buffs from being calculated - all math happens simultaneously
• This applies to all effects in the game, not just passives - there is no "snapshotting" except where explicitly stated
• Debuffs like Stupefy snapshot the target's current Might value at the time they're applied, then apply that reduction continuously
