Design a ruleset

Define the core contest action here, then refine or add more actions in the JSON below. Every action selects participants by attributes, resolves a contest, and applies a weighted outcome.

Create a starter action, then use the JSON editor to add weighted alternatives, feature gates, penalties, injuries, or more phases.
