After applying this Upgrade to your Aetheric Energy Projector, you can better control where the spray hits, allowing you to avoid your allies and deal additional damage to specific enemies.
When you use the Aether Spray ability, you can designate up to 2 creatures per Proficiency Boost that you possess in Aethertech Lore that are within the area of the ability. All creatures you designate this way are immune to the initial effects of that use of the ability and any ongoing effects it may have until the start of your next turn.
You can spend 1 charge of Aether Flux when you use its granted ability to deal +1 Bonus Die of damage to one of the targets in its area. You must decide which target takes the extra damage before you make your attack roll.
