Whatever your party may be facing, you'll need to know who's on first. What better way to do that then say... I don't know... A custom initiative tracker! On our whiteboard signs, they're usable with wet or dry erase and clean up easily with a whiteboard cleaner or paper towel and water.
Variations on the Initiative Trackers include player count or lettering changes, we recommend 2+ your party size, so the Dungeon Master has room for placement.
