[RPM] What are some ways to make Mind and Body and sense effects harder to pull off?

[Raekai]

Hey, all.

I love RPM, but one thing that has been troubling me is how damn easy it is to read minds or tell if someone uses magic or is an alien. In my major setting, it's important to be able to hide those things in order not to be found out by a group which want to purge aliens and mages (but only those that aren't allied with them, of course). It seems pretty easy to be able to throw out a Lesser Sense Body and detect if someone is an alien in disguise. Of course, you can resist, but what if you don't want to? Let's say that you're suspected of being an alien, they take you in, and, to prove your innocence, you won't resist their detection spell.

I've thought about making countering magic pretty common. That's not a bad idea. But then they could just sense if you have any magic on you.

I've also considered making Mind and Body effects harder to do. As if using magic to affect willful beings is much harder than using magic to affect something that doesn't have a will, like stone. But I don't know how to go about that. Still, they could sense magic, or I might be able to argue that magic has a "will" of its own.

Or making sense effects harder to do. Or maybe even just getting rid of sense effects altogether, but would that break RPM? How would I go about establishing telepathy and other useful sense effects in that case? This seems like it might be the best idea for my personal needs, but I don't know what else I might need to adjust for such a radical change.

Any ideas are welcome. Even if they don't end up fitting my setting, I'm not too worried about that. New ideas are really helpful.

Thanks!
