How does damage work in combat - does it reduce a creature's might, and can you cast Gust on a creature after it takes damage in combat?

Ruling: Damage does not reduce might. Damage counts up separately, and when damage equals or exceeds might, the unit dies. You cannot cast Gust on a 6 might creature just because it took 3 damage in combat - it still has 6 might.

Sequence:

• All damage in combat is dealt at the same time
• You must play Gust during the showdown (before combat damage) to affect combat
• You cannot play spells after the showdown is over but before combat damage
• After combat resolves, all units everywhere heal to full

Nuances:

• Gust can only target creatures with 3 might or less as their printed/modified might value, not creatures that have taken damage
• You cannot do a standard move into a showdown in progress, but you could move a unit with effects like Ride the Wind
