This is a Deployment Tactics topic.

Of course, reducing the potency for aoe only and if it could be deployed.
Otherwise, 650 on single target is fine and shouldn't be changed, 300 would be insignificant

In the same manner, noct Ast has innate +15% on all healing spells, while aspected helios heals for 150 potency and adds a shield totalling 150% of hp restored. 150 potency x 1.15 x 1.5 = 258,75 potency shield. Adding Earthly Star on top of that is 978,75 potency effective healing. Every minute, as opposed to Scholar's Deployment which is every 2 minutes.

Now, Ast is insanely powerful and should imo as an Ast main be nerfed (or the other 2 brought up to the same level), but with current numbers, deployed Adlo + Excog would hardly be op. Unless Adlo crits, which would basically invalidate Excog in most situations if it only hits below 50% and isn't changed to an explosion in the same manner as Earthly Star. Still, i never suggested being able to deploy both, but I understand that's not easy to understand.
