Does damage dealt to a unit reduce the amount of damage it deals in combat, or does it still deal damage equal to its original might value?

Ruling: A unit deals damage equal to its current might value. Damage marked on a unit does NOT reduce its might or the damage it deals. Only effects that explicitly reduce might (like Stupefy) will reduce the damage dealt.

Nuances:

• Damage and might are separate concepts - a unit with 5 might and 3 damage marked still has 5 might and deals 5 damage
• To kill a unit, you must deal damage equal to or exceeding its might
• Damage markers are removed at the end of combat and at the end of turn
• Might reductions only persist if the effect specifies a duration (like "until end of turn")
