Can Frostcoat Cub destroy a unit with only 2 Might (or can units with 0 or negative Might survive without damage)?

Ruling: Units only die when they have non-zero damage marked on them that is greater than or equal to their Might. A unit with 0 or even negative Might will not die until it takes at least 1 damage.

Nuances:

• Units can go to negative Might under current rules
• Even if a unit's Might is reduced below zero (e.g., to -1 or -2), it remains alive as long as it has no damage marked on it
