The changes you've suggested sound like a good place to start. You can call them whatever you please and arrange them as you see fit (I wasn't meaning to suggest names for them), it'll just be easier all around if they aren't quite so lumped together. You can have as many individual abilities as you like, so don't be shy about separating them. Let me know when you've made the changes and I'll be able to properly asses the abilities.

I can't tell you the exact math because yes, hushhush quietquiet, but I can tell you that you that as your profile currently stands it would almost certainly be too powerful for level 2. With the changes you suggested it might be fine though, it will depend on the specifications we discussed.
