I tried using an Armorer potion for the first time yesterday. It said that weapon and armor improvements would increase by 30%. So I try to improve a pair of eleven boots without the potion first. I can improve them from 20 to 32 (exquisite). Then I reload, drink the potion, and try to I improve them again. I can still only improve them to 32. Shouldn't it improve to 35 (20+12*1.3)?
I later try the same thing with a potion of enchanting and get the same result (i.e. my enchantments are not any stronger).
Am I doing something wrong?
