Greetings everyone! This is my first time on the forums and I am visiting you with a dilemma in my plot line. My story is populated only with incorporeal spirits (ghosts.) I find that there is a need for certain battle sequences in which the spirits will fight with each other. Naturally, they cannot harm themselves in any way physically but I need some way in which they can interact in a "harmful" way with each other to give the reader a sense of drama. I've thought of some kind of telekinetic attack but I can't seem to convey a sense of danger when the characters cannot die. Thanks for any input ahead of time and yes, I'm crazy for attempting to write a story like this.
