# Accessories

DIY accessories have two characteristics to consider:

### Category

Accessories can be in one of **four categories:**

* Common
* Rare
* Legendary
* Mythical

### Level and Progress Bar

Each accessory has a **level** from 1 to 10, with a **progress bar** at each level.

When you receive an accessory as a reward for the first time, its level will be 1. As you receive the same accessory as a reward again, its progress bar will fill up. Once it's full, you can increase the accessory's level, up to level 10.

### XP Calculation

XP for each accessory is calculated based on its category and level as follows:

* Common: 2.5 XP per level
* Rare: 5 XP per level
* Epic: 7.5 XP per level
* Legendary: 10 XP per level

You can equip or unequip accessories from your DIY character at any time. Your DIY character's XP will be the sum of the XP from each equipped accessory.
