Can a defender assign all combat damage to a single attacking unit to avoid killing other attackers with death triggers, or must damage be distributed to kill all units once lethal is reached?

Ruling: Combat damage must be assigned to reach lethal on each unit before moving to the next unit. If the defender has enough power to kill multiple attackers, they must kill all of them and cannot concentrate all damage on one unit to avoid death triggers.

Sequence:

• Assign damage to the first attacking unit until it reaches lethal
• Once lethal is reached on that unit, damage must be assigned to the next unit
• Continue until all damage is assigned
• The last unit can take excess damage beyond lethal

Nuances:

• Any unit before the last can only be dealt exactly lethal damage
• The final unit in the damage assignment order can receive excess damage beyond what's needed to kill it
