Ghostbusters NL can harness a significant number of resources to permanently keep out ghosts and related supernatural phenomena. Most of these methods are technical, such as mood slime or anti-ectoplasmosonic transmission equipment (compare it to, say, an ultrasonic cat repeller), but we may at times also employ ritualistic, religious, or mystical methods: Spirit-repellent objects, symbols, or physical or verbal expressions—e.g. talismans, totems, seals, amulets, fetishes, relics, and/or spells—, are not dismissed as long as they achieve their goal.
