What ability is this, and what class uses it?

[Abriael]

I read that paragraph about 10 times over and I did not understand one thing you just said. It's like you purposely threw jargon at me (that I happen to know fortunately) to try and make a point but it made absolutely no sense. But I'm not just going to be mean and give you the benefit of the doubt that you actually had something meaningful to say... in which case, could someone please translate this?

I'm afraid that's not my fault. The explanation was quite clear, and in fact others understood it with no problems.
