I am 116 and I am very very very close to bishop. And I want to know how I should go about bishop. I am thinking for my first 3 skills I will go.

1 AR, 1 MW, 1 Buff Mastery.

I am thinking of going MW 10 then Buff mastery 10 then AR 10. Since every skill starts off with mastery level 10. From there, what books are priority and actually realistic. I'm sure I won't be getting MW 20 easily but I might save 5-10 points for it just in case I ever get a book. What skills are Priority for a bishop, besides the obvious rude comments saying HS IZ MAXEDLOL U DUN NED NE MOAR SKLZ.
