When a unit with 2 base might and +1 might from a buff is affected by Watched (which gives -3 might), what is the final might value?

Ruling: The unit will have 1 might total. Might-increasing effects are applied before might-decreasing effects, and Watched snapshots to the value needed to reduce the unit to 1 might.

Sequence:

• Start with 2 base might
• Apply the +1 might buff (arithmetic layer, increasing effects first)
• Apply Watched effect, which snapshots to -2 might (the amount needed to reduce the unit to 1 might)
• Final result: 2 + 1 - 2 = 1 might

Nuances:

• Watched snapshots to whatever value gets the unit to exactly 1 might, not necessarily the full -3 might
• The snapshotted value applies continuously until end of turn
