If that's the case I'd say that Immersive Potions isn't needed with PERMA. Immersive Potions is for those who wants to play vanilla Skyrim, but doesn't want infinite instant healing :tongue: In the description for PERMA I found this as a feature: "Make alchemy effects work over time". Now I don't know if PERMA handles potion effects like Immersive Potions does or is as flawlessy implemented, but either way there will likely be some compatibility issues when it comes to the perks.
