I should make a secondary note of the 'fantasy' tag, I feel.

While not quite Shadowrun [which was a major inspiration], I would like to clarify a bit; No such thing as magic, but stretching the laws of physics is alright.

shotguns with suppressors? Nah, they heard you.

You want to swing off a chandelier and dropkick a guy out a window and stick the landing all while having time to brush your hair and look good while you're at it? [Exaggeration slight] alright that's chill.

Drop lightning out the sky with your mind? ehhh that's not cool.

That's basically the census I reached with myself when thinking up the boundaries. Keep it realistic but feel free to have some fun with it within that category.
