I'm excited. The guy overheard my conversation about wanting a mages' book and he decided to buy it for me. Many thanks to him for doing so. ^-^ It'll be good use once i get ancients again.
if i get the tome i may sell this, because the tome is "free" and gives infinite water runes. but i think i'll enjoy the mages' book's bonuses for now (+15 - mages' book; +10 - tome of frost)
