The element die has sides for Earth, Air, Fire and Water. It is primarily designed for roleplaying or storytelling games, where it can be used to figure out the kinds of magic an enemy might have, or what their weaknesses are.
Unlike the regular d4, the roll is shown by the symbol on the top face when the die is rolled. This uses the patented d4 design by William Sides, used here with Bill's permission.
This die was added to the system since some of the cards shown on the cards page were rendered, so may not on those illusrations.
