More questions about skillz

Fake only protects against damage, so the shadower will be sealed.
Smokescreen protects against all attacks and any effects caused by attacks. If Pianus's dispel/seal is caused by a damaging attack, then you're protected against it.
As for Lilynouch's damage reflect and smokescreen, I went to find out and lost a charm because of it. Yay for science. Smokescreen does not protect from damage reflect. I'm guessing this is because it doesn't appear as an attack that actually hits you, but just a decrease of your hp. Didn't test it with ME because I assume it'll have the same result and I don't feel like dying in the name of science more than once a day.

So I take it you'll still get dispelled/sealed. Because those are skills, and they have nothing to do with Pianus' attacks.

Thanks for some definitive answers =) In the name of Science!
