This mod contains a Legion Helmet with horizontal crest. Apart from that there are some Legion Dragon Upgrades, such as a new female cuirass, caped versions of both male and female cuirasses and a new helmet with horizontal crest.

As a base for the female cuirass I used: 'A Female Imperial Dragon Cuirass V11 by The Bloke'

The caped cuirasses use capes from 'JaySuS Capes'

I take no credit for that what I did not make! This mod does not include an .esp file. Some .nifs are not game-ready and need some work! All files do have textures and normal maps though!

I can recommend these mods to upgrade the Legion Dragon armor even more:

'Gold Dragon Horse Armor Textures by Zira' (This requires the DLC 'Horse Armor')
