Pretty much all a summoner can ask for in a body, there only remains one question imo..
Will the 'increases blood pact damage' affect merited abilities such as heavenly strike? If it does, it's the first piece to do so apart from Avatar: Magic acc/att. Which would be cool.
Pretty sure it will include all bloodpacts, going to be interesting to see how this "blood pact damage" will compare with the magic acc and att from the ACP body
