Just one week, how is that unlucky? I on average gained one per 3 week until I beat 120....
This scroll is VERY different from previous ones. I got all my sages by being at 99 or something for a few weeks, but this one... until you pass 120, you won't get much at all, even if you are at 119 for months. It's not you, it's not bad luck, it's the drop rate.
