## How it works

Supplies used on adventures run out regularly. Replenishing them connects preparation to repeated gathering.

## Variants

### Action → reward

<a id="consumable-supply-loop"></a>

- Gather ingredients and prepare supplies → replenish potions, food and ammunition. <a id="consumable-supply-repeat"></a>
- Prepare consumables for a particular challenge. <a id="consumable-supply-option-2"></a>
- Choose inexpensive stock or a powerful rare effect. <a id="consumable-supply-option-3"></a>

## Design example

Before an expedition, the party gathers herbs and prepares healing potions for several fights.

## 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.
