Ehn the rune formation being drawn finished, a small circle of wind built up within it. Someone pulled the thin elf away who had drawn it just before a spark of flames erupted within creating a small tornado of flames. It was an interesting reaction within from the runes, but clearly an intended one.
The small wind and fire tornado did not change its course or anything else about it. Mostly because whenever it started to, earth and water mana would guide it to repel it from doing so. Effectively creating a stationary way to trap or to burn something. It could also be used as a deterrent.
Walker could think about the farm lands which would deal with pests. The insect type monsters would easily fear the flames like this. So, if these rune formations were put around farms when a swarm of them were on the way, everyone would be a little safer. Furthermore, it would protect the crops better than having constant patrols of guards.
