When a buffed Fiora (at 6 might from a +1 buff, making her mighty and giving her shield) is defending in combat and the attacker uses Stupefy (-1 might), does Fiora end at 4 might or 5 might?

Ruling: Fiora ends at 4 might. When Stupefy is played, the layers system re-evaluates and checks ability-altering traits (like Shield) before arithmetic. Since Fiora would be 4 might without Shield's +1, she doesn't qualify as mighty and loses Shield, leaving her at 4 might total.

Sequence:

• Stupefy applies -1 might, triggering a cleanup cycle
• Ability-altering traits layer evaluates first: Fiora is 4 (base) +1 (buff) -1 (Stupefy) = would be 4 without Shield
• Since she's not mighty (5+) without Shield, she doesn't gain Shield
• Arithmetic layer resolves: 4 +1 -1 = 4 might final

Nuances:

• Shield cannot be what makes Fiora mighty; she must be mighty without Shield to gain it
• Without Stupefy, the cleanup would loop: first she'd be 4, go to 5 with buff, become mighty and gain Shield, then go to 6, and cleanups would cycle until nothing changes
• This applies to any unit that requires mighty status to activate passive abilities
