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 Cutter after completing one of Petra's Forgotten Temple quests.

Chapter 7 introduces Abel who allows players to assemble G8-G10 gem-cutting books after completing the Forgotten Temple quest 30 times.
