It's been a while since I have done one of these, but today seems to be a good day for it.
The very first Class Struggles I did way back in August of 2015 was about the Mystic class.
This week Wizards of the Coast just released a new mystic class to their Unearthed Arcana feature.
You can get it for free for your D&D 5th edition games.
The new mystic is partially like a monk, but more in tune with the Psionic classes of 4th edition. In truth, there is a lot here that people should be able to see previous edition origins. But that is getting ahead of myself.
The mystics are Psionic characters. Not the first if you consider Monks still to be Psionic, but the first fully Psionic class complete with Psionic Strength Points/Psi Points.
Mystics are given certain "quirks" or taboos. These are odd personality traits that they must obey as part of their solitary training. I am reminded (and not for the last time) of the Wu Jen from 1st edition Oriental Adventures or the Mystics from the D&D Rules Cyclopedia.
Powers are split up into Talents (which use no points) and Disciplines (which use points). Talents are open to all mystics, but Disciplines are usually focused by Orders. In many ways these have a familiar feel to them. On first glance, they are most similar to the Psionics used by +Richard LeBlanc in the Psionics Handbook Mystic.
Orders are "flavor" but like many of the "subclasses" (1st ed terms) or "kits" (2nd ed terms). I have to say I REALLY like these. Again, this is where D&D 5 plays like "D&D's greatest hits".
We get Orders of the Avatar (emotions), Awakened (mental), Immortal (body), Nomads (like the Akashic Brotherhood), Soul Knife (combat, 4e return), and Wu Jen (Elementalist). So lots and lots of potential here.
The one thing they need is a more esoteric sort of mystics like the ones found in +Alexander Macris' Adventure Conquer King Player's Companion Mystic or even the Mystic from +Joseph Bloch's A Curious Volume of Forgotten Lore or Adventures Dark and Deep. Or even the mystics in the Dragonlance 3.5 setting, though those were more of godless clerics.
One could easily do an Esoteric Order that also gets some cleric spells like the Wu Jen get "arcane dabbling".
There is a lot in this class I find fascinating to be honest. Can't wait to try it out. Not just in terms of the class, but how Mystic Orders fit into my game world.
