How do damage and might reduction interact differently in combat? Does a unit with marked damage still deal its full might in combat?

Ruling: Damage marked on a unit does not reduce its might, so a damaged unit still deals its full might value in combat. However, effects that explicitly reduce might (not damage) will reduce the amount of damage that unit deals.

Sequence:

• When damage is dealt to a unit, it is marked on that unit
• If marked damage equals or exceeds the unit's might, the unit dies
• During combat, the unit still deals damage equal to its current might value (not reduced by marked damage)
• At the end of every combat, all units on the board are healed and marked damage is removed

Nuances:

• Damage (like from Hextech Ray or Skysplitter) marks damage on a unit but doesn't reduce its might for combat
• Might reduction effects (like Accelerated Watcher's -3M) actually reduce the unit's might, which reduces combat damage dealt
• A 4M unit with 3 damage marked will still deal 4 damage in combat and trade with another 4M unit
