Best Book to get

I got advanced final attack on my bowmaster because it was one of the key pieces of damage in ascension builds (it's maxed like first). By the time I'll need spirit link or illusion step, I'll probably not even be playing anymore or just not worrying about it. I need to remax bowmastery and hurricane now, but it's cool because I maxed those out earlier (except hurricane 30. Need to pass my 30 book).

Also took advanced bless for my bishop so he could be the buff mule of the century. Got me covered with MW, Advance bless, the super shield thing, heal and HS.
