[1.09u][BALANCE] min INT for many spells is way too high, and others issues of the book
Seriously, even the lowest level spells require a 16 int, and things like arcane arrow required 27. Most champions (this is not a problem for sovs)- start out at around 8-14 int, so champions would have to be lvl 6, and put all their points into INT for imbuing them to be worth anything.
Many low level spells need to be lowered in terms of INT requirements. Elemental books especially.
Another thing, I'd like to see channelers start with one of the elemental books also at times, like they used to, in addition to what they start off with. Also it needs to be easier to get the spellbooks channelers start off with via research.
