When Nine-Tailed Fox reduces a unit's Might by 1, and that unit later loses a static buff (like Assault from Captain Farron), does the -1 reduction persist and potentially bring the unit to 0 Might?

Ruling: Nine-Tailed Fox's -1 Might effect applies once when it resolves. If the unit could have its Might reduced at that moment, the reduction is applied permanently. The restriction only applies at the initial determination of whether to apply the -1 Might, not continuously afterward. Units can survive at 0 Might as they require nonzero damage to be defeated.

Sequence:

• Nine-Tailed Fox trigger evaluates whether the unit has more than 1 Might
• If yes, -1 Might is applied to the unit
• The reduction persists even if the unit later loses static buffs
• If the unit drops to 0 Might from losing buffs, it survives unless it takes damage

Nuances:

• Units don't die from reaching 0 Might; they must receive nonzero damage to be defeated
• The restriction on Nine-Tailed Fox (and similar effects like Stupefy) only checks at the moment of resolution, not continuously
