After playing too long with the original -far too worn - dice, I decided to find dice online. I saw many people offering dice with various buffs; extra skulls, extra shields, etc. I saw the one with a double white shield and thought it would be good to use, as my kids struggle to stay alive in the game. The problem is that those dice changed the odds as other sides were also changed.

This die design keeps the original ratios - 3 skulls, 1 black shield and 2 white shields. Only one of the white shield sides is a double white shield.
