I don't know if this is the right place but it seems best to put my question here. In my Chaos army I have a Chaos Spined Beast. In the rules for this CC monster it references the daemonic gifts in the current Chaos codex, which as you may know will be replaced in Sept. My question is what is the normal procedure for continuing using this model i.e. do I use both codices together or just ignore the Gifts option?

Also for the Marks of Chaos it lists should I use the old ones e.g. MoT makes it a sorcerer, or the new ones e.g. MoT gives +1 Inv Sv?

Any help you can give will be greatly appreciated.
