wait..what do you mean potions stack too? do you mean if you drink 2 potions of Fortify Smithing 5%...you'll get a total of 10% ? so..i can drink 10 or more of them at once for over 100%??
Sorry, no, didn't mean to say it like that. I meant more that the enchanted gear stacks with the use of potions for similar effects.
The point being that you can use fortify enchantment potions to make better fortify alchemy gear to make better fortify enchant potions to make better fortify alchemy gear to make even better fortify enchant potions to finally make the ultimate fortify enchant/fortify smithing gear, and then fortify smithing potions.
Use those to make the best gear. And then use the excelent fortify enchant potions to enchant the newly crafted gear as best as possible. Game = broken. Such gear is easily superior to what can be located in game (even with how skills improve it). Fully enchanted/smithed daedric armour being worn by someone with no heavy armour skill is better than daedric armour being worn by a heavy armour master.
