Gem characteristics

Gems are divided into classes similar to the equipment types. The higher the class, the bigger the bonus. A gem's shape and background color also depend on its class:

• Simple — a shard with a gray outline
• Usual — a diamond with a white outline
• Unusual — a square with a green outline
• Rare — a circle with a blue outline
• Epic — a triangle with a purple outline
• Legendary — an octagon with an orange outline
