These stones are encrusted into equipment items and serve to imbue items with new characteristics.

There are 6 types of precious stones:
 

• Agate - increases maximum health.
• Topaz - increases endurance.
• Ruby - increases strength.
• Diamond - increases attack.
• Sapphire - increases agility.
• Emerald - increases speed.

Encrustation stones have development level. The higher level, the higher the properties of a stone will be.

A stone levels up if synthesized with a stone of analogous type and level. The maximum level of synthetization for an encrustation stone is 11.  

Precious stones can be found in stashes during exploration of locations, collect in the form of a reward in the “Dungeon”, get them from an arena box or buy in the premium store.
