Hopefully this is the right place to post this question.
My question is, could I take a necron overlord, and give him some items from the regular Necron 7th edition codex, along with something like the solar thermasite from the mephrit dynasty relics of the war in heaven?
Say, for example, I was running the decurion. The overlord had some items from the mephrit dynasty, would he be able to take the solar thermasite to give him reroll 1's in saves?
Thanks
