If a unit has damage marked on it from a spell, and then Watcher reduces its Might, does the unit die?

Ruling: Yes, the unit dies. When damage marked on a unit is greater than or equal to its Might, it dies. Might values can change, and if they decrease while damage is marked, it can kill the unit.

Sequence:

• A 4 Might unit has 3 damage marked on it from a spell
• Watcher is played, reducing the unit's Might to 1
• The unit now has 3 damage marked and 1 Might
• Since damage (3) >= Might (1), the unit dies

Nuances:

• There is no "health" stat in Riftbound; damage and Might are separate values
• Damage marked on a unit does not reduce its Might value
• A unit dies when damage marked equals or exceeds its current Might, regardless of how the Might changed
