Hypertuned/Resonant

[Belhi]

Honestly I think its unclear. Resonant seems to mean artificial Echo but Hypertuned could just mean supersoldier. Most Hypertuned enemies we face are augmented physically rather than Aesthetically from what we can see. I would not be surprised to see a Doma castle HM with us heading down into the labs under the castle after the waters recede during the patches.

I heard it pointed out in a live letter and had a look in game to conferm: Inferno seems to have the third Garlean eye.....

It is, admittedly, very uncertain. There is no buildup or explanation for Hyptertuned enemies beyond an Imperial soldier telling Yotsuyu they had performed a "procedure" on Grynewaht "as Lord Aulus instructed." Other than that and the Journal and Mock-up Grynewaht minion making it clear he has extensive cybernetic augmentations, absolutely nothing about Hypertuning is explained in-game.

If it weren't for that third eye, Inferno could easily be written off as just some horrific, cybernetically enhanced genetic monstrosity made by Aulus or whatever. But that third eye raises a lot of questions...
