## How it works

Prolonged repetition of one source reduces yield or raises cost, changing the next activity choice.

## Variants

### Variants

<a id="diminishing-returns-options"></a>

- Reduce yield when repeating one action. <a id="diminishing-returns-option-1"></a>
- Raise the cost of consecutive upgrades. <a id="diminishing-returns-option-2"></a>
- Restore efficiency after changing activities or resting. <a id="diminishing-returns-option-3"></a>

## Design example

After intensive harvesting, a site depletes and another becomes more attractive.

## 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.
