Gems

Gems are custom items that work like accessory cards. Each type of gem has its own effect. Gems in eRO have different grade levels, ranging from G1 to G10.

Players can cut gems at Gem Cutting after completing one of Petra's Forgotten Temple quests.

Chapter 7 introduces Abel who allows players to cut G8-G10 gems after completing the Forgotten Temple quest 30 times.
