I didn't see a change in my last 2 skill advancement(88-90). I currently have the first 5 perks of alchemy and only want to use the enchantment potion. So does anyone know if there what the difference is between a skill of 90 versus 100?

Post about this previously, basically effort required to legitally get alchemy to 100 is not worth it for enchanting+smitthing exploit. The enchantment potion is like 1-2% better which really won't affect your overall outcome much. Just start at 90.

Idk but I would think that there has to be. That wouldnt be right if the wouldn't of.

Cheers
