Critical Hit d20 Ice Mold
Savings throw time - whoops you rolled a 1, you are critically drunk.
A great ice cube mold that makes one large d20 ice cube (2.4" in diameter) that would lok great in your soda or mixed drink.
Everyone in your gaming group is going to be jealous of your d20 ice cubes. They look awesome and last in your drink a pretty long time because of the mass they have.
It would be really cool to have a slightly bigger version that you could make cupcakes out of. You could use this to make chocolate d20 dice as well, but the pinhole that the chocolate would go in is a little small. Doable, but tricky.
What might be easier is making jello jigglers out of this. Think about a couple dozen jello d20s at your next RPG or tabletop gaming session! Fun.
In any case, good luck with all your future dexterity checks!
