StarPool Dice Mechanic

From publisher blurb: One of the drop in resolution sub-systems for StarCluster 3, In Harm's Way: StarCluster, and Commonwealth Space. The StarPool Sub‐System uses d20 dice pools to play. All rolls are made with d20s, and the Sub‐system uses the StarPool Character Sheet along with the Character Generation Worksheet. User note: freely available on the publisher website as a distinct file.
