What happens if you use Zarya's barrier on a Reinhardt with his barrier activated?
If you apply Zarya's Projected Barrier (ally shield) on a Reinhardt with his Barrier Field (large shield) where does the damage get applied?
The Projected Barrier or the Barrier Field?
If the damage is frontal and intercepted by the Barrier Field, the Field will absorb it. If the Barrier Field breaks, or the damage is from a direction Reinhardt is not blocking, then the Projected Barrier will absorb it. Only damage absorbed by the Projected Barrier will contribute to Zarya's Energy level.
