I'm looking for whatever resource or info on where the earth/Rock material comes from for a earth blast. Or any blast for that matter. My GM is new to the class and I need to supply the back up info for any rule or thing that is in this class but havnt found this info.
Lol he is looking to counter some of my toons abilities and thinks if there is no earth material within so many feet I'm screwed.
I have read one discussion that it is from the ethereal plane but no resource I can confirm this.
Thank you.
