The Evolith system allows adventurers to customize their equipment using stones that can be obtained from notorious monsters throughout Vana'diel. An Evolith is an ancient stone that harbors an elemental power similar to a crystal. By collecting different stones, adventurers can outfit their gear with stats and bonuses that complement their roles in battle.
Evolith is obtained by completing new NM hunting regimes accessible from Hunt Registries in various areas of Vana'diel.
For a detailed list of Notorious Monsters and the Evolith Stones obtained from their hunts, see Notorious Monster Evolith Chart
Up to three Evolith stones can be attached to eligible pieces of equipment. To see whether a piece of gear supports Evolith, trade the gear piece to the Synergy Engineer dispatched in each city.
Should you wish to replace an attached piece of evolith with one offering different benefits, this may be done at time via synergy. It is also possible to remove evolith slots entirelyâ€”thereby returning the equipment to its original stateâ€”through synergy using a dedicated item. Note that in both cases, the previously attached piece of evolith will be lost.
