No. Would be interesting as a Binder class or subclassDo you want to base it on hermetic esoteric alchemical traditions, and include conjuring and binding spirits and elementals?
All I know of Thibaults Circle is that it was a Renaissance sword style (?) based upon geometry and the circle. So, noDo you want Thibaults Circle inspired alchemical sword fighters with a deep knowledge of anatomy, body mechanics, and geometry?
I guess what I want is something that covers Chinese external alchemy, Latin Alchemy, Indian alchemy, Arabian alchemy and such, but without the religious mysticsm aspects ( or maybe Chinese (internal), Indian mysticsm, and Hellinistic spirit binding which you had mentioned) as some of the available subclasses.Do you want an advanced poisoner and item-based healer? Maybe with noxious gases, abilities to remove conditions fluffed as being via chemistry and stuff like smelling salts to end a stun?
Or something else entirely?
