Equipped items change attributes and available actions. The player chooses a useful combination while accounting for each item’s drawbacks.

1. The item has both a benefit and a drawback
2. The summary shows the combined effect of equipped items

- Show the net effect of a replacement, including lost bonuses.
- Connect properties to gameplay decisions as well as rarity.

## How it works

Equipment changes character properties, while affixes and sets connect item selection to actual behavior.

## Variants

### Mechanic variants

<a id="t053-variants"></a>

- An affix grows stronger under a stated condition. <a id="t053-v1"></a>
- A set changes a rule after enough pieces are worn. <a id="t053-v2"></a>
- Weight limits combinations of heavy equipment. <a id="t053-v3"></a>
- Replacing a property preserves a valuable item base. <a id="t053-v4"></a>

## Design example

Light boots improve attacks after dodging, but the full set rules out a heavy shield.

Prototype check: Test item comparisons: players should see a bonus trigger and the cost of replacing equipment.

## Context and limits

Role-playing systems connect character identity, party composition, equipment and consequential choices. 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.
