When assigning combat damage to multiple defending units, must an attacker assign lethal damage to all units before moving to the next, or can they choose to assign non-lethal damage and leave units alive?

Ruling: An attacker can choose how to distribute damage among defending units and is not required to assign lethal damage to each unit before assigning damage to others. Damage assigned to units that survive will be healed after combat resolves.

Nuances:

• This allows attackers to avoid triggering death triggers on units they don't want to kill
• Non-lethal damage typically has no lasting effect since it heals after combat
