A six sided die to keep track of a heritor's Blood Burn modifier in Frostgrave - Ghost Archipelago. It shows the numbers 0, 3, 6, 9, 12 and 15.
The 6 and 9 are underlinded to make them easier to distinguish.
I also wrote the numbers in a way, so that the top of each number points to the next higher side.

Osprey sells a nicer version, so check their shop or your local freindly gaming store.
