It's as if, suddenly, she just knows how not to embarrass herself. She can read the room more, that customer service smile, and that's fine, this is a shop, no need to go feeling awkward about it-
"Oh. I like this. I can- Hmm! One moment..."
She plays a complex scene in her head, losing herself in it and filling out all the details. It's... Not easier, exactly, she still has to clearly visualize everything and figure out how it should react, but... Yeah her usual patterns for body language and clothing design and facial expressions and tone of voice all seem so amateurish, now.
She wills it to life, a startlingly complete image of Sinnah, her bored yet interested expression, the way her fingers twitch slightly when she moves, the curling flick her tail does- And how the shopkeeper's eyes dart to it, and what parts of it draw the eye- She makes the Sinnah illusion scoff dismissively, then vanish.
It's not even just the illusions though. Wearing this- And maybe she should have been a little more hesitant to wear mind enhancing magic but too late- It feels like walking down the street openly back on Tirra would be less overwhelming, less embarrassing. Like she can let the opinions of idiots wash over her, unaffected.
