All right, the thread derailed quite a bit, and nobody is talking about this UA anymore. I suspect nobody even read it properly.
How in the Nine Hells they could think this is remotely in theme with psionics, or even any possible new take on it? Heck, how did they think this would be something fun in the first place, even if it wouldn't be associated to psionics?
We have trinkets, they are nice, entire adventures can be had about them, but look what this trinket becomes for the "psionicist":
I believe you still didn't read all of it properly, because you smelled grognard rant, so I will quote the quote, the part you should really know:
"a figure of luminous psychic energy, with your psionic focus hovering within. "
And I believe you forgot already what the psionic focus is, because again, it must be juat some grognard ranting about this, so I will quote the previous quote:
"One morning, did you wake up with it humming under your pillow?" - It's a freaking trinket.
The sidebar doesn't finish where I stopped quoting, it goes on about this "focus" possible forms, clarifying they have no idea what they are talking about, except that it's a trinket:
"Perhaps it’s a childhood memento"
So to cast/manifest powers (ah no, sorry, they must be "psionic spells") as any mentalist/psion/mystic/psychic would do in any world (that is, without uttering freaking magic formulas accompanied by gestures), you have to become a "figure of luminous psychic energy" (looking however you damn please BTW, as specified in the rules text later) with a "childhood memento" (OR ANY OTHER OBJECT, AS LONG AS IT'S A FREAKING MATERIAL OBJECT, because clearly that's how you unlock the immaterial powers of the mind) "hovering within" this new "luminous" and "obviously magical" body of yours. And this is 6th level.
Do we really need to talk about WotC publishing adventures or splat books, or can we just tell the designers that this joke is not funny, already??
