Well, it turns out that they are much harder to fix; starting with the fact I can't even find everything relating to them. I'm not trying to do anything fancy here, but I need help.
So for my example, could someone walk me through what I would need to do to change the effect and description of "Fists of Steel". While I'm fine with the base unarmed boost, I would like to add an effect that makes the player immune to being Disarmed if they are wearing Heavy Armor Gauntlets (like Iron, Ebony, etc.) to give it a more general and practical use - IE: Make people actually WANT to take the perk.
So I'd like the Perk Description to read in the Skills Menu, "You do increased unarmed damage and are immune to disarming effects while wearing heavy gauntlets", and in the Magic Effects menu read "Do increased damage with unarmed; immune to disarm effects" while wearing said heavy gauntlets, and I'd obviously like the perk to have that effect.
