Do the mystic psychic spells like “Psionic Blast” have any visual effect? At present it sounds like Mystics have a whole range of spells that are completely invisible and unpreventable. they should be default be noticeable – not intended to be undetected as a default

mystics “Occluded Mind” causes a target to believe one statement. Is this essentially a death sentence?I.E. "you want nothing more than to die as quickly as possible". It seems open-ended, unlike the Suggestion. Or limited like suggestion

belief and action aren't the same thing – for instance, NPC might want to do, but first needs to make peace with friends, make arrangements

If a mystic dropped Adaptive Body psi focus after extended use, do the effects (no food or air) “carch up”? no

yes, filtering it through the settings is part of the next design step; also need to keep in mind Eberron

Which has the more sciency approach to psionics: Dark Sun or Eberron? I never tried Eberron myself, so didn’t know it had psi until recentlyIMO, Eberron. I see Dark Sun treating it more as a form of magic, while Eberron's tone is a little more toward trying to understand/study

Took a short vacation. Might have designed everything I need to run a 5e Dark Sun campaign. As one does.

The original Dark Sun boxed set is a master class in world design. Kudos to @TDenningauthor and Tim Brown.

is awakened mind considered magic? Can others tell u are using it? Can they tell its u that is using it on themYes to all three

will psionic disciplines only be accessible to mystics or will there be subclasses like the EK and AT which draw from wizrd listquite likely will be subclasses like that, though depends on final design

Mystic Question: Can Giant Growth discipline allow a 25 ft reach? (+5 (focus) + 10 (Giant Form) + 5 (Reach Weapon) + 5 (base))?I think that adds up, but further playtesting might pull back on it

Mystic Arcane Dabbler: When the spells are cast, do they require V, S, M components as appropriate? good question – I'd assume yes
