How to disguise a psionic power

[Frogman55]

Lets say you want to manifest a power on someone, say Charm, or Read Thoughts; can you hide that? Suppress the display, so that people don't know its being cast? Or perhaps to disguise the source of the casting?

I feel like there aught to be a psionic equivalent to silent/still spellcasting.

There is. It's a Concentration check built into Psionics.

Concentration reference.

Dispense with Displays
Despite the fact that almost every power has a display, a psionic character can always choose to manifest the power without the flashy accompaniment. To manifest a power without any display (no matter how many displays it might have), a manifester must make a Concentration check (DC 15 + the level of the power). This check is part of the action of manifesting the power. If the check is unsuccessful, the power manifests normally with its display.

Even if a manifester manifests a power without a display, he is still subject to attacks of opportunity in appropriate circumstances. (Of course, another Concentration check can be made as normal to either manifest defensively or maintain the power if attacked.)

From here.

Perfect. I knew it was somewhere but I was failing in an embarrassing fashion.

Further afield, would be the Crawling Tattoo.
More difficult + longer psicraft check to identify it.

That's what this subforum is for.
