When Bellows Breath targets multiple units at the same location, but some units move to a different location before resolution, what happens to the damage?

Ruling: When Bellows Breath resolves and targeted units are at different locations, you choose one location and deal damage to all targeted units at that location.

Sequence:

• Targets are chosen when Bellows Breath is played (all must be at the same location at targeting)
• Targets cannot be rechosen after initial selection
• On resolution, if targets have moved to different locations, choose one location
• Deal damage only to the targeted units at the chosen location

Nuances:

• The "same location" requirement is a targeting restriction, not a resolution requirement
• If one unit remains on battlefield and two move to base, you can either damage the one on battlefield OR the two at base
• This ruling applies similarly to other cards with group location restrictions like Facebreaker and Foxfire
