d66 magic dice

Here is a pdf version.

It is most fun when the players don't know that odd results are good for them and even results are bad. Mine don't even know that it is a d66 roll and not a total. When they roll an even result and there is a referee choice, I often ask the player to choose something that might be good for their character, then turn their choice against them. For example, on a 14 I might ask the player to choose an animal they want to turn into, then have their enemies turn into that animal instead.
