Can Dragon's Breath spell damage enemies that do not have a clear path to the caster?
The PHB page 204 says:
To target something, you must have a clear path to it, so it can’t be behind total cover.
The Dragon's Breath spell is unique in that the both the touched creature (user of the breath) & the enemies are targets:
Dragon's breath has two sets of targets: the creature you give the breath weapon to and the creatures in the area of effect created by the spell
What if the enemies have total cover from the caster, but not from the user of the breath?
