To put it simply, this is a mod for a 420 damage sword with the Chillrend perk. I didn't mean for it to be THAT powerful, but...at least it's not 1,000 damage!...Yeah, doesn't really make a difference. I also made a MUCH weaker version in the optional files section.
This mod was made for Tobuscus from youtube. Search for him, because he is FUNNY. (Sponsor!) Anyway, the sword can be crafted at skyforge, you need glass smithing, a daedra heart, elven gilded armor, a steel sword, 3 diamonds, firewood, and an iron dagger. (The stuff you need is made up of some things from Tobuscus' inventory by his 158th part of skyrim.) You don't need the 3 diamonds and firewood for the weaker sword. There are also a bunch of books in a barrel at the bannered mare, upstairs. Just search inside a barrel and you should find books that raise your smithing (if you don't have the perks required for the sword) and a book I created based off of Tobuscus' adventures and info that could really help him out.
I believe there are no conflicts with any other mods, so don't worry! Just have fun with the sword!
