Dont read that info's becouse 1: they are outdated (from previous versions) and 2: didn't even got the numbers myself.
But for u to know, i dont care about those numbers, if it were for me, I really wouldn't put even which level they're for, becouse I'm not going to test most of them, like this scarabs, so numbers are just orientative. You think 40+ is not enough? go on lvl 50~60 then.
Yours,
Dekk.
