[RPG] What dice do I need to make for a Pathfinder player

From the wikipedia article on dice.

The full geometric set of "uniform fair dice" (face-transitive) are:

• Platonic solids, the five regular polyhedra: 4, 6, 8, 12, 20 sides
• Catalan solids, the duals of the 13 Archimedean solids: 12, 24, 30, 48, 60, 120 sides
• Bipyramids, the duals of the infinite set of prism, with triangle faces: any even number above 4
• Trapezohedrons, the duals of the infinite set of antiprisms, with kite faces: any even number above 4
• Disphenoids, an infinite set of tetrahedra made from congruent non-regular triangles: 4 sides
• "Rolling-pin style dice" (also called "rolling logs") are the only way to make dice with an odd number of flat faces. They are based on an infinite set of prisms. All the (rectangular) faces they may actually land on are congruent, so they are equally fair. (The other 2 sides of the prism are rounded or capped with a pyramid, designed so that the dice never actually rests on those faces.)

I believe you are talking about a rolling log/rolling pin style dice.

In a "dice pool," one considers each die individually, rather than as a collection of components to be summed. As an example, an attack in the HERO System might do 8d6 damage; to resolve it, you'd roll eight six-sided dice and add them up to produce a number between 8 and 48. In a die pool system, you might see how many of the dice showed a 5 or a 6 on the top face, and count those as "successes" toward a benchmark.

Rolling vs. a target number can be used in both die pool systems and otherwise. In HERO, for example, you roll 3d6 and sum them, trying to stay below 11 (or an otherwise modified target). In Deadlands, you use your die pool and select the highest rolled die, comparing it with a target number modified by the difficulty of the task at hand.
