If Lee Sin (centered with 7 might) and another buffed unit (5 might) are both targeted by Icathian Rain (Lee Sin 4 times, other unit twice), will both units die during cleanup even if Lee Sin takes the last instance of damage? Does the order of triggers matter?

Ruling: The order does not matter. Both units will die. Once Lee Sin dies, the other unit will have its might reduced (losing the centered buff) and then die in the cleanup after the one where Lee Sin dies.

Sequence:

• Lee Sin takes damage and dies
• Cleanup occurs and Lee Sin is removed
• The other unit loses the might buff from Lee Sin's centered ability
• Cleanup loops again and the other unit dies (now having insufficient might to survive its damage)

Nuances:

• Cleanup loops continuously until nothing happens, which is why both units die even though they don't die simultaneously
