When Watcher's effect is applied to a unit with 2 power, does the unit defend for 1 or 3? How do -might effects get applied - are they timestamped at resolution or do they linger?

Ruling: When Watcher applies -1 might to a 2 power unit (minimum 1), the debuff is 'snapshotted' at -1 might. When that unit later defends alone and gains +2 from Wuju Bladesman's passive, it will defend for 3 total power.

Sequence:

• Watcher enters and applies -1 might to the unit (reducing 2 power to minimum of 1)
• The -1 debuff is locked in/snapshotted at that value
• When the unit enters combat alone, Wuju Bladesman's passive activates, granting +2 might
• Final defending power is 3 (1 base after debuff + 2 from Yi's buff)

Nuances:

• All single-use debuffs work via snapshotting - they lock in their value when applied
• Wuju Bladesman's ability is passive and only applies while defending during combat
• The scenario assumes Watcher enters before combat begins (Yi's buff isn't active yet)
