The Martial Adept is a homebrew conversion of the Tome of Battle: The Book of Nine Swords classes from D&D 3.5e: the Crusader, the Swordsage, and the Warblade. I was inspired by the layout of the July 2015 Unearthed Arcana for psionics, and I moved the different schools from Tome of Battle into concentration-based stances that give access to point-based maneuvers. I consider this class primarily finished, in terms of mechanics. If you manage to playtest it at all, be sure to leave me some feedback!
