"I don't actually know how to walk you through getting around what I've got," he comments, and he's not sure he would if he could, "but I imagine the practice is just helpful for us both?"
There's a pattern to it. In the middle of combat it'd probably be hard to find the weak points in his defenses, but sitting in a bar in peace and quiet gives her all of the time in the world to find them. And there are weaknesses.
They might need vocabulary for this. Veron doesn't have any to speak of.
It's slippery, but only in certain "directions", and that means that if she can catch threads she can just slide right through -
(There is an undercurrent of 'they were about to be under attack against a force that would likely completely crush them and kill everyone involved that was on the losing side.')
Wasn't there a way to detect someone reading his mind? He could have sworn there was a way to detect someone reading his mind, he just can't recall what it was, it was all - practicality. This is what you need to know so an illithid doesn't turn your brain into goo.
"I... am not used to describing it aloud? I can bounce the memory if you want it?"
The Seer had given it a very fancy and official name, but he cannot at all recall what it was. Just how to do it. That's the important part.
"Oh, I see what's happening," he says after studying it for a little while. "Hm, I wonder if I can account for that. Are you willing to humor me trying stuff?"
He puts his defenses back up, and then tries what he's thinking of.
The first few times don't work, but after a third, the "directions" of the slippery start changing.
"Oh, good. For a bit there I thought I wasn't on to anything at all. ... Would learning defenses help you at all? I imagine you have your own, but mine might help add something unexpected to them, since I'm from far away and have weird techniques because of that."
"I actually have really good natural shielding, but I wouldn't mind having better."
Down go the defenses!
He is doing this in this sort of way for the slippery in "directions," it involves this hard-to-put-into-words-thing, and then to make it switch "directions" he just does the same thing, but from a different "start" point, like this, see? And he can switch that periodically. It takes a bit of concentration, but it'd be worth it to keep someone out that he wants out.
According to the illithids he has a trickier mind than usual, but he doesn't know how to box that quality up and put it into a teaching format.
"I can't really help you, my shields are self-maintaining and I don't do a thing about it."
She did help him get a better shield, anyway! Which is pretty great in itself.
Right, bit too much, out of his head please, he'll explain this out loud. It'll make more sense that way. Also he can skip over the things he would like to skip over.
(He was briefly a slave, for instance, that was unpleasant.)
