When playing Imperial Decree with a 3 might unit attacking 3 units with 10 might each at a battlefield, can you choose to deal 1 damage to each unit to kill them all?

Ruling: No, you cannot deal 1 damage to each unit. Imperial Decree does not modify the concept of Lethal Damage, so you must still assign enough damage to kill a unit via normal means before assigning damage to another unit.

Sequence:

  • Assign lethal damage (enough to kill) to the first defending unit
  • Only after assigning lethal damage to the first unit can you assign damage to the next unit
  • Continue until all damage is assigned

Nuances:

  • Imperial Decree works best when attacking with low Might units, as only 1 damage is enough to kill even a 10 Might unit
  • The effect works both ways (affects both players)
  • Sending in units one at a time could be a good strategy when using Imperial Decree
