This is a "combat die" for the classic board game HeroQuest.
As the game is out of print since 1993, but has still many fans, replacement playing material is much searched after. For the "combat dice", showing 3 skulls for hits, two white shield for heroes' defence and one black shield for monsters' defence, you can use this model. The design is faithful to the original, the depressions are a bit deeper and the edges a bit sharper to fit the plastic printing material (the original dice were made of wood). Heroquest was published by MB, now owned by Hasbro. No copyright violation is intended by pubishing this model. It is just a help for fans who want to play this long out of print game.
