Chaos Armor and protection
Unless I remember wrong the protection is not part of the chaos armor boon, but is an additional effect on the Chaos Armor skill.
Well, if the combo is different from the staff skill, it should have another name.
Or else chaos armor /= chaos armor? Its rather illogical to have two forms of chaos armor.
I can to some extend understand that protection is not applied by deafault when chaos armor is applied. Maybe that would be OP.
But to not have it as a random boon when beeing hit? Why should chaos armor be handicapped. 1) its not logical and 2) it makes the effort of creating combos not worth it. Protection is vital to the use of chaos armor, imo.
