After applying this Upgrade to your Aetheric Energy Projector, the energy it projects becomes more intense, and you can amplify that even further by pushing more energy through it. The damage dice of the Device’s Aether Spray increase to d8s.
You can spend 1 charge of Aether Flux when you use the Device’s Aether Spray ability to gain a +2 Bonus to any damage rolls you make as part of that activation of the ability.
