The D12 (twelve-sided die)

The d12 is a regular dodecahedron — twelve pentagonal faces around a silhouette that reads almost spherical next to the pointed d8. In the tray it is the profile die: its round, heavy look tells you at a glance that a set is filling out, and a shelf of complete sets starts to look uniform once most of them can show a d12.

Functionally the d12 is just one more face a complete set requires, but its size gives it a practical cost. It is the die most likely to be mistaken for decoration when it sits alone — a single rounded-coloured shape with no obvious partner. The fix is the same as everywhere else in the shop: colour first, then material, then place it with its set rather than on a display of loose dice.

When a set is close to finished and only the d12 and the d20 are left, the two tend to be the two largest pieces on the floor. Sweep visually for size before you sweep for shape; the big round dice cluster, and finding them together usually closes the set in one trip. When you are budgeting a session, the d12 is also a good early stock: it is large, distinctive and rarely confused with anything else in a mixed tray, so placing it first turns a chaotic pile into a recognisable partial set fast.

How it fits the shop

This entry is part of the dice sets section of the guide. The d12 is the pentagonal dodecahedron, twelve pentagons around a round-ish silhouette. It is the face that reads as "complete set" at a glance on the shelf.
