I ordered some more Monster dice from Videador, and also picked up some undead Turn and Reroll markers:
Along with my order, I received a free gift! It was a 30mm lipped base with a side peice that came complete with a magnet embedded. This works very nicely in conjunction with one of Impact's metal cored balls. The ball carrier can be stood in the lipped base, or otherwise the ball can be removed and placed on the players base as normal.
