Do you trust me? Sabrina gave me suggestions so if they're not scary, we can blame her.
I have an idea, and I don't know if your magic can do it, but maybe coupled with my magic they could work together. I use a lot of runes and glyphs right? What about setting harmless "traps" on the path and when they're stepped on, they set off an illusion or sound or something in the woods far off?
