So uh, about the free skillbook at level 70

I was rather stupid and chose Ishtar's Ring 30. Looking at the skill build for Mercedes level 120+, I see that was probably one of my very silly decisions (I'M SORRY ).

So uh, is maxing Ishtar's Ring (to use the book before it expires in February - no way in hell can I reach 150+ before that) or at least getting it high enough so that I can use the book going to be the end of the world? I'm not all too familiar with Mercedes past level 120.
