You can find/buy boots with muffle and disenchant them to use at the enchanting table. User enchanted muffle is 100%.
Well punch me right in the face. You're right!
I think the gist of the topic is the nightengale armor looks awesome but the enchantments on it leave alot to be desired, is there any way to remove them and customize the enchantments to somthing useful.
I had hoped that there were unenchanted versions of the armor pieces I could console command into my inventory. Unfortunately I've found no such thing. When the CK hits, that's the first thing I'll likely fix.
