d12s

A d12 (short for "dodecahedral die") is a polyhedral die with twelve faces, commonly used in tabletop role-playing games (RPGs) such as *Dungeons & Dragons* (D&D). Each face is typically numbered from 1 to 12, though some variants may include special symbols or additional values. The die is shaped like a regular dodecahedron, a geometric solid with twelve identical pentagonal faces, twelve vertices, and twenty edges.

D12s are frequently employed in games to simulate high-level challenges, such as determining the outcome of difficult combat maneuvers, skill checks, or critical successes. Their higher maximum value (12) compared to standard d6s (six-sided dice) makes them useful for scenarios requiring greater randomness or higher probabilities of success. They are also used in probability-based mechanics, such as determining the success of rare or extraordinary events.

In addition to RPGs, d12s appear in other games, including board games, wargames, and probability simulations. Some players and game masters (GMs) prefer d12s for their aesthetic appeal and the tactile experience of rolling a larger, more complex die. They are often paired with other polyhedral dice, such as d4s, d6s, or d20s, to create varied and dynamic gameplay.

D12s come in various materials, including plastic, acrylic, and metal, with some featuring translucent designs or custom engravings. They are available in standard sizes, though miniatures and specialized versions exist for collectors or niche applications. Proper care, such as avoiding drops and excessive moisture, helps maintain their accuracy and longevity.
