1. The affix has its own T4 tier
2. The upgrade applies to the chosen affix

- Show the improvement and every cost before confirmation.
- Explain the upgrade cap and any chance of failure separately.

## How it works

Materials are spent on successive enhancement levels of an existing item. Cost and success probability are separate design choices.

## Variants

### Action → reward

<a id="enhancement-levels-loop"></a>

- Gather materials → raise an item’s enhancement level. <a id="enhancement-levels-repeat"></a>
- Raise levels with guaranteed results and increasing cost. <a id="enhancement-levels-option-2"></a>
- Prepare protection materials before a risky upgrade. <a id="enhancement-levels-option-3"></a>

## Design example

The player gathers crystals and upgrades a sword from enhancement level three to four with guaranteed success.

## 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.
