NAF – New artifacts with unique properties.

I tried it, and it works, but not everything. Stats are added, but effects like a bonus of 500 experience per day and ±500 gold per day don't work. Also, after finding the components of Armageddon's Blade, I didn't understand how I was supposed to combine them into one.

And the mana effects didn't work either (of course, it's version 3.1 of the game without mods).
