@phil777 It's not balanced at all, with the skill level 1, you could get 1 skill every 4 days easy, and now only once every 18 days, his seems like a downgrade to me. Well, not so much a downgrade, because it is better to be able to target precisely and certainly the skill you want, but it seems a bit to big since you're supposed to have upgraded the skill 9 times.
Still, I'm surprised that they didn't make more of a ruckus than that, it was a greater Demon and she soloed it, yet they don't seem to take it much into consideration.
