I recently got back into the game, figured I had to at least finish what I started. Problem is, the last boss is a pain in the ass. I know everyone says just parry him, it's easy! But for me, it's not. I cannot for the life of me get the timing down and I'd like to progress into the NG+ quite badly. I'm SL 76 and would appreciate if anyone could help me out! I just want to beat this guy and get it over with.

First off, I'm sorry if this has already been posted before but I need help!

Here's the story:

Currently I'm level 27, and I just found some mace that has a fire enchantment on it that does 25 points of fire damage. I want that enchantment! My problem is that when I was a much lower level, I must have disenchanted a weaopon that only does 10 points of fire damage. Now I can't disenchant this mace because it says I already have the enchantment! How in the world do I switch them, if that is even possible. Did I miss out on much stronger enchantments?
