So, having had a long time away from it, I love the basic structure and ideas, it’s a complex Spellcasting monk, mechanically.
It lacks fluff ribbons, and it needs more “esoterica”.
I’m also not sure about where I wanted to go with the subclasses.
I think the subclasses want to be Schools in an almost anime sense of “the guys from the Cat School are fast and hard to hit, and they hit hard, but they aren’t nearly as tough as the Bear School” type stuff.
The School of The White Lotus gets a Fighting Style choice between Dueling and Defensive, and a protective buff when they have a hand free. They’re the most Martial School, the most focused on direct weapon mastery.
The School of The Goetic Circle are Binders, who gain extra spells from Tasha’s Summon X line of spells, and special buffs and abilities that revolve around interacting with a willing ally. They also get Magic Circle, Dispel Magic, Glyph of Warding.
The School of The Sohei focuses on polearms and simple weapons, and on fighting supernatural evil. The closest to divine we get.
The Hermeticist is a mystic alchemist first and foremost. A hermetic philosopher with a sword.
