A Drow Pursuit tracker for Out of the Abyss. Put 3mmx6mm circular magnets in each of the holes (and an optional magnetic strip on the back for attaching to a DM screen). Then, you can use any kind of small magnet to keep track of the party's pursuit level. I only have four places for magnets here, since level 0 pursuit doesn't need to be tracked and level 5 pursuit results in combat immediately, but I've included the Sketchup file for ease of remixing.
