Does a character with 0 Might die immediately, or only when they take damage?

Ruling: A character with 0 Might does not die immediately. They only die if they have non-zero damage marked on them that equals or exceeds their Might.

Sequence:

• Might reduction reduces how much damage a unit can take before dying and reduces the damage they deal in combat
• Damage is marked on units and is compared against their Might during cleanup
• During cleanup, units with non-zero damage marked that equals or exceeds their Might are killed
• A unit at 0 Might with no damage marked survives

Nuances:

• Might reduction and damage are different mechanics - reducing Might is not the same as dealing damage
• A unit with damage marked still deals its full Might value in combat (damage doesn't reduce combat damage dealt)
• It's possible to have units with 0 or negative Might through combinations of effects
