Spirit Howl
Template:Obsolete Spirit Howl is a monster-only spell which afflicts you with the Howl status effect. As long as you suffer from this, spirit wolves will rapidly generate and will seek you out by the shortest path possible. Eventually the status effect will end, dismissing all spirit wolves not currently in your line of sight, and there is a fixed cap on how many spirit wolves you can face in a given game.
