Gianna Heron is finally in follower format. I've had a couple of requests for this to be made into a mod and I'm finally honoring those requests. She is a pretty powerful follower and can be found in the encampment outside of Fort Dawnguard with the Dawnguard refugees. I'll put her basic information on attributes and such below.

Race: Nord
Combat Class: Blade - Basically in the CK she will fight like Delphine. She is proficient with all weapons and both armor types and will favor whatever weapon works best for the situation shes in. 
Stats: +350 to base Health and Stamina; +50 to Magicka
Spells: I did not equip her with any spells. She is basically a ranger warrior as her lore goes
location: Dawnguard encampment - with the Dawnguard refugees.
Default Armor: Gianna has custom leather armor and custom dawnguard boots and gauntlets. Their stats are below.
   - Gianna's Dawnguard boots and gauntlets. base armor 20 each; base weight 1.5
   - Gianna's Leather Cuirass. base armor 50; base weight 8.
By default G's armor will probably outclass anything you equip her with so she will not be able to switch to whatever you put on her unless you temper it a bit. There is a trick with Nether's Follower Framework to get her to switch gear I can explain if you message me in chat I will describe it.
Default Weapons: Gianna actually has some custom weapons that I made for her. They use vanilla ebony weapon textures and assets but have enhanced stats for increasing her combat effectiveness. They are as follows:
    - Gianna's Ebony Sword: base damage 25; base weight 8
    - Gianna's Ebony Bow: base damage 25; base weight 8
    - Gianna's Ebony Arrow (100); base damage 25; base weight 0.10

I strongly recommend Nethers Follower Framework to use alongside Gianna and I am also using Somewhere in Between vanilla armor replacer which changes the appearance of her cuirass, boots and gauntlets. Gianna Is a powerful follower and I recommend that you play with her on at least master if she is in your party. She will outclass most enemies right out of the box on adept and expert. If you need help troubleshooting issues with the mod message me in the comments section. Otherwise she should work right out of the box. I'll be posting more pictures of her as I playtest her some more. I hope you enjoy Gianna Heron!

UPDATE: Gianna will now use whatever skin textures you are using instead of Lovergirl.  I chose to do this to cut down on her file size.
