This is why (for instance) Fireball or Symbol refers to creatures caught in the area as "targets," even though Fireball initially targets a point and Symbol initially targets an object.

Some relevant references:

That said, Spirit Guardians is still great and well worth flying around with.
Eh. Double SG doesn't work for more RAW reasons in that the same creature cannot be buffed/debuffed by identical spells.

It's purely for style as all of your spirits also have mounts now!
