What is this?
A craftable greatsword version of the paladin's best friend, Dawnbreaker. In vanilla and Reliquary of Myth flavors.

Why does this exist?
For the longest time, whenever I played a paladin type character, I used Break of Dawn as my primary weapon, due to the fact that Dawnbreaker (hands down the best undead slaying weapon in Tameriel) was a one-handed weapon. Then I discovered Zim's Immersive Artifacts, which introduced the ability to switch from a one-handed Dawnbreaker to a far superior greatsword version (created by Leanwolf ) and beefed up it's power and usability. However, much like everything else in life, shiny new mods were released that also improved Dawnbreaker (and the other, lesser Daedric Artifacts). One of which quickly became a permanent addition to my load order, Reliquary of Myth. Unfortunately, it doesn't have the option to switch from the boring one-handed Dawnbreaker to the BBS (Big Beautiful Sword) that is the greatsword version. So I decided to remedy that, and this is the result.

Standing on the Shoulders of Giants.
(Aka the how and how of this mod)
With Leanwolf's permission I took his standalone Dawnbreaker greatsword mod and tweaked the esp. I removed the weapon from Forelhost and simply made it craftable using the standard version of Dawnbreaker. Simple as that. This allows you to switch between the one-handed and greatsword versions of the weapon whenever you want using a forge, keep in mind however (and this should go without saying), that by doing so you will lose any tempering you did to the previous version of the weapon. For the Reliquary of Myth version of this mod, I tweaked the greatsword's value for consistency and added the Dawnbreaker keyword to keep things nice and copacetic. Plus, I added a condition to both versions of the mod that would keep the crafting option hidden unless you have either one of the swords in your inventory.

Tl;dr
1. Acquire Dawnbreaker
2. Go to forge
3. Craft greatsword Dawnbreaker
4. Go hit undead things until they're dead again

Compatibility:
This mod should be compatible with literally anything. Including mods that change the vanilla Dawnbreaker. In fact if those mods change the DA09EncDawnbreaker enchantment, those changes should work for the greatsword version as well. This mod is also 100% compatible with Leanwolf's standalone greatsword Dawnbreaker mod.
