When Irelia with Marching Orders attacks and uses Repeat, does she die after the first instance of damage (if she takes lethal damage) or does she survive to complete both instances before dying?

Ruling: Irelia survives to complete both instances of Marching Orders' effect even if she takes lethal damage during the first instance. Units only die during cleanup, which occurs after the entire spell resolves, not in the middle of resolution.

Sequence:

• Irelia deals 5 damage to the first target and takes damage equal to that target's might
• Irelia deals 5 damage to the second target (can be the same or different target) and takes damage equal to that target's might
• After the spell fully resolves, cleanup occurs and Irelia dies if she has damage marked equal to or greater than her might

Nuances:

• Repeat is paid once as a cost and doesn't create a second copy of the spell; it makes the spell "bigger" by adding the effect a second time to the same resolution
• You can choose the same targets or different targets for the repeated effect
• There is no cleanup in the middle of spell resolution
