If Fiora gains Mighty during combat (after being declared as a defender), does she get the +1 from Shield?

Ruling: Yes, Fiora gets the +1 from Shield when she gains Mighty during combat, even after being declared as a defender.

Nuances:

• Shield and Assault are passive "while" effects, not triggered "when" abilities
• They do not use the chain and are always active when their conditions are met
• If Fiora gains Mighty from Shield itself (like from Fortified Position), she gets both bonuses at once
