Where is my character's Evasion Rating coming from?

I noticed on the character screen I had some evasion rating which was a surprise.

I wanted to know where it was coming form.

I stripped naked and it's still there, so it wasn't my gear. Doesn't look like any nodes I have in my skill tree grant any either.

Is it innate to all characters? I tested and it doesn't appear Dex grants any so I guess I'm curious was as to why I have any at all. Granted it's low but I was just curious.

All characters have 30 evasion rating by default. Every level up it grows by 3. For example at 11 level it's 60 evasion rating.
