This is an alternate recolor of the Man at Arms character.

Place the included folder in your
Windows > Program Files (x86) > Steam > SteamApps > common > DarkestDungeon > heroes > man_at_arms folder

If you wish this as a replacement rather than an additional color, change the designation "M"
to A, B, C, or D

If you already have additional colors, make sure that none are named "M" prior to moving this folder. 
You may change it to any unused letter.
