the problem is i already disenchant an 8% fortify smithing from a necklace early in the game.. after a while i found an 17% fortify smithing necklace.. can i change the % with the one i already disenchant before ? because if i enchant fortify smithing to an equipment in my current state its very hard to get a high %... since it start at 8% even if i use fortify elixir it will only add up to 17%... help me... >.< should i start a new game again ? haha T.T
