She would be the "new stone giant" essentially. The power is considered a primal "pre-god" power from the dawn of time. It can't be destroyed, but with her goddess abilities she should be able to handle it. Controlling it after gaining it all at once may be a little difficult at first, so she should expect to have a couple of mistakes, but with some effort she should be able to figure out how to not accidentally disintegrate souls separated from bodies. (Dead or astral projecting.)

Yes, the inventory spell will work on her kettle!
