This wound tracker has a simple, ergonomic design which allows you to keep track of your turn wounds. In short, you can use it in the game to mark what you like; in the back, there is a small slot that can be used to insert cards for any cards, notes, buffs, nerfs with the same principle (remember that the card slot is 0.9mm).
It's perfect for wargaming, but what about other types such as D&D or similar games? Simple, the insert of the 16mm die there are scales for a multi-sided dice.
Now all you have to do is print and play, good luck and have fun!
