When I installed FOV, I noticed the version changed from 1.03 to 1.04. I'm pretty sure some skills were edited at that time during the installation. I have also installed to hotfix, due the infinite loading screen bug. I don't think there was a skill change when I installed the hotfix.
I could be mistaken, but I'm pretty sure the skills magic blast and explosive arrow are less powerful then they were before.
I must say my post is confusing since a new patch has been launched.
