If a 2 might unit is buffed to 3 might and then reduced to 1 might by Watcher's ability, what happens when the buff expires?

Ruling: When a buffed unit is reduced to 1 might by Watcher, the buff is already factored into that 1 might. If the buff expires afterward, the unit goes to 0 might but does not automatically die.

Sequence:

• Unit starts at 2 might, receives +1 buff to become 3 might
• Watcher reduces it to 1 might (the calculation is 2 + 1 - 3 = 1, with the buff included)
• If the buff expires, the unit drops to 0 might
• The unit only dies if it takes damage while at 0 might

Nuances:

• Equipment works the same way as buffs in this interaction
• Being at 0 might does not automatically kill a unit; it must be damaged to die
