"The nerf assists in making alternate paths of power gain a bit more even. 4% codex of power, or 2% to fire damage for significantly less AA's? If you are a rogue probably not, but if you are a magician, that may be a bit tempting." -Cyzaine
Please dont take this as a flame Cyzaine - I think your great. I just want to know if there is any point at all, in getting a none Codex of power, Tome. I have ben arguing this back and forth with guildies and i would like to know.
Personaly i would say it needs to be less then 1/3 of the codex exp as you also use magic damage as well as pet dmg on a mage. But that is up to debate. If it takes more then 1/2 the exp of a codex, then it is compleaty useless for anyone that hasent allready compleated 5 power codex. And that isent really just a matter of opinion.
I wish I had a flame tome or a frost tome and i would test the hell out of this today. Some of you l33t guys please test it =).
