I'll need some more time to a deep dive, but very interesting so far! I always like when homebrewers take the time to explain their design decisions, and I thought your overall concept of splitting the fantasy and sci-fi concepts apart is excellent.We've rebalanced the Mystic class for our campaign setting, as we always do. I'd be very interested in this group's feedback.

The Reddit post outlines some of the major technical changes we made to the class, and the document itself discusses the reasons for our major flavor and class redesigns.
Is the one on the DMguild the same?Just chiming in to flag this is a necroed thread and that there are no news on the Mystic right now
If you're half as tall, with the same limb proportions, and still walking with the same gait at the same pace, yeah, you'd cover half the ground. If you were shrunk to teeny size, but still 'walking' at the same speed, you'd either be a blur of tiny steps, or, more likely, each step would be a prodigious leap, like a flea.P.S. diminutive is still ridiculous to me; at the very least it needs to have its movement speed nerfed to the new size. half size half speed. quarter size quarter speed etc. seems appropriate if a little too generous really.
I like that you combined all of the summons to one (at least thematically) but the description is weak. and binding spirits to the elemental sounds a bit witchy and magical to me. maybe something more: you have learned that all of matter and energy consists innately of a balance of shadow and light. by subtly manipulating this balance you invoke a primal rift through which elemental energy eagerly enters the material plane. The elemental disappears if you lose concentration because the balance automatically reverts to normal banishing the elemental immediately.
I stopped looking at the revised disciplines, for now. but it seems to me that the disciplines are not allocated in a balanced way. the psion particularly seems to get the best abilities: summon stuff, giant growth or shrink, psychic blast and black dragon breath.
teleportation is relatively easy for a mystic to do while melfs acid arrow or tensers floating disc or magic missile is relatively difficult. like chemistry and biology trying to do the same thing. some will have to put for tremendous effort while the other relatively little effort to do the same thing.
