Secret work.

In my studies I heard of an item created by alchemists of yore called an “Interdiction torch”. While replicating its effect was tricky, I eventually created the “Interdiction ritual” as a tribute to them. What it does is “Repel” any living thing that gets within it's range. After realizing a small error, I changed it to where humans are the sole exception to its effect. Being flung back by your own ritual has a tendency to make you want to tweak it, I've found. While I couldn't make it “Free” like the alchemist's of yore, it only costs 1k LP to start and 10 LP a second for a run time fee. Rather cheap, all things considered.
