I noted earlier that the skill book reduced damage after pumping, but the first time thought that maybe mistaken. But the second time I compared the damage on the same Unit before and after pumping. And to my great disappointment my first fears were confirmed in the first rage damage to the demon fell from 666 to 664 and after the second pumping from 664 to 661! Not only that improvements are costs about a million and a half million last! But all this stuff compared to what I reduced damage by 20% on my character for my own big money!
Ask to fix an error on a character and return Mag her damage + increase damage by 20% since the book dropped 20% of damage. My nickname in the game is Wartorn ! I hope you fix that BIG error!
