1. This expedition has a 25% chance to provide a key

- Explain what a key unlocks and when it is consumed.

## How it works

One repeatable activity awards consumable access to another. A key establishes the cost of attempting the next reward.

## Variants

### Action → reward

<a id="access-keys-loop"></a>

- Farm available activities → gain entry attempts to a boss or dungeon. <a id="access-keys-repeat"></a>
- Collect named key parts from different sources. <a id="access-keys-option-2"></a>
- Allocate limited passes among rewards. <a id="access-keys-option-3"></a>

## Design example

Three seals from border outposts combine into a treasury key.

## Context and limits

A systematic RPG grind reference: 110 mechanics and 330 variants in 18 sections. Four layers answer different questions: what the player repeats, what develops, how rewards arrive and what constrains the loop. It covers single-player RPGs, ARPGs, MMORPGs and adjacent management and accumulation systems. Every mechanic has an explanation, variants and a hypothetical example; coverage, combinations and verified game observations follow the catalog.
