WrathVisualAdjustmentsMod VS WOTR_FxTweaks

By any chance did you get Visual Adjustments instead of Visual Adjustments 2? The latter is working fine for me.

Anyway, if you feel like giving it a shot here's the link, but do make a backup save before messing around just in case: https://github.com/BarleyFlour/WrathVisualAdjustmentsMod

If you're on PC and don't mind using mods Visual Adjustments 2 can do that already. Plus a bunch of other stuff that Owlcat will probably never implement.

I don't think so. There's the github site for the old version of the mod which lists some of its features but I don't think they're all implemented yet.

Third question: Ugh, in-character outfits are very limited in this game. There is the Visual Adjustments mod that allows you to pick any of the available outfits freely, independent of class or armor type (e.g. you could have your caster run around in what looks like plate) and add/remove other visual effects. The downside is that this does not magically make more armor available. Still, there might be stuff that matches what you want, especially if you look into monster outfits (not sure if incubus outfits, for example, are available as clothing or only as complete body transmogs... would need to check).

Visual Adjustments.

When I played with a gestalt character, I got the feeling that that toy box feature was a bit on the buggy side, so I never tried respec. However, if you just want to change the hair style, I think the Visual Adjustment mod can help: https://github.com/BarleyFlour/WrathVisualAdjustmentsMod

FX Tweaks so your character isn't a ball of blinding light (or a dozen giant prismatic dragons) when buffed
