I have a few ideas for some new traits that would help bring some abilities or traits back into some balance.
Deflect; Converts true damage into normal damage.
Shield (# or X%); Reduces damages by a certain amount or percent. Kind of like what armor, stone skin and granite skin do now for skull attacks.
Negate: Cancels fast, empowered or any other trait that gives a bonus mana at the start of the battle. This is getting badly abused. Developers really need to look at this seriously.
