Loot distinguished from the environment - Back rarity colors with text or shape and show how to pursue a reward. - [Grim Dawn](https://store.steampowered.com/app/219990/) ## How it works A loot system distributes rewards through conditions and probabilities, connecting uncertainty to a clear search direction. ## Variants ### Mechanic variants - Loot tables connect sources to possible rewards. - Weights alter an item's relative frequency. - Guarantees limit unsuccessful attempts. - Duplicate protection narrows an unfinished collection. ## Design example A station can drop a needed module, while ten tokens allow obtaining it directly. Prototype check: Test long failure streaks and guarantee clarity; do not present an average wait as a promised completion time. ## Context and limits Progression changes player options and goals; rewards should explain new decisions and preserve useful stopping points. Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map. ## Connected materials - Sources in the selection: [State: Game Programming Patterns](https://gamemechanics.pro/en/resources/#resource-state-pattern) (key: resource/state-pattern) ## Sources and provenance Original bilingual editorial overviews authored for gamemechanics.pro on 2026-10-20 and reviewed on 2026-10-21.
