Does Rabadon's Deathcrown increase Bellows Breath damage from 2 to 4 for each target, and does this apply when repeated or targeting multiple locations?

Ruling: Yes, Rabadon's Deathcrown increases Bellows Breath's damage from 2 to 4 for each target. This applies whether targeting up to 3 units at one location, repeating the spell to deal 4 damage twice to 3 units, or spreading 4 damage across 6 units at two different locations.

Sequence:

• Bellows Breath deals damage to each of up to 3 targets at the same location
• Rabadon's Deathcrown increases each instance of damage from 2 to 4
• If repeated, each target takes 4 damage twice
• Can target different locations to affect up to 6 total units
