The Eureka Weapons are a series of ultimate weapons that adventurers can obtain in Final Fantasy XIV: Stormblood.

The Forbidden Land of Eureka is wracked with chaotic aetherial energies. Gerolt, the legendary blacksmith, can use them to create ever more powerful weapons.

All of the materials for Eureka Weapons can be found in the Forbidden Land of Eureka. Unlike previous ultimate weapons, materials for Eureka Weapons can be gathered with any class.

Anemos weapons[]

The first iteration, the Anemos weapon, can be acquired in Eureka Anemos by using Protean Crystals to empower the Antiquated weapon obtained for reaching level 70. Protean Crystals can be obtained by completing FATEs in Eureka Anemos, or rarely as regular enemy drops. The final upgrade requires Pazuzu's Feathers, which can be obtained by completing the FATE "Wail in the Willows" or by trading in 300 Protean Crystals per Feather. Completing the Anemos weapon adds a glowing effect. They were introduced in patch 4.25.

Pagos weapons[]

The second iteration, the Elemental weapon, can be acquired in Eureka Pagos by using Frosted Protean Crystals and Pagos Crystals to further empower the Anemos weapon. Pagos Crystals are obtained in the same manner as Protean Crystals within the bounds of Eureka Pagos. Frosted Protean Crystals can be obtained by building up "light". Nearly every FATE and enemy in Eureka grants a varying amount of light upon defeat, and once a bar of light has been filled the player will receive a Vitiated Aether Crystal, which can be traded for a Frosted Protean Crystal. The final upgrade requires Louhi's Ice, which can be obtained by completing the FATE "Louhi on Ice" or by trading in 50 Pagos Crystals per Ice. Completing the Elemental Weapon changes the weapon's appearance, but removes the glow. They were introduced in patch 4.36.

Pyros weapons[]

The third iteration, the Pyros weapon, can be acquired in Eureka Pyros by using Pyros Crystals to further empower the Elemental weapon. Pyros Crystals are obtained in the same manner as Protean Crystals within the bounds of Eureka Pyros. The final upgrade requires Penthesilea's Flames, which can be obtained by completing the FATE "Lost Epic" or by trading in 50 Pyros Crystals per Flame. Completing the Pyros weapon adds a glowing effect. They were introduced in patch 4.45.

Additional secondary stats can be randomly added to the final stage by exchanging two Smoldering Protean Crystals, which are acquired by farming light in the same manner as in Eureka Pagos. These stats can be re-rolled repeatedly by exchanging another two Smoldering Protean Crystals each time, until the player gets a set of stats they are satisfied with.

Hydatos weapons[]

The final iteration can be acquired in Eureka Hydatos by using Hydatos Crystals to further empower the Pyros weapon. Hydatos Crystals are obtained in the same manner as Protean Crystals within the bounds of Eureka Hydatos. The final upgrade requires Crystalline Scales, which can be obtained by completing the FATE "Crystalline Provenance", and unlike the equivalent items from prior steps cannot be acquired by any other means. Completing the base weapon changes the weapon's appearance, and the final Eureka upgrade adds a glowing effect. They were introduced in patch 4.55.

A Eureka weapon can be further upgraded into a Physeos weapon by acquiring Eureka Fragments from the Baldesion Arsenal, though this only increases its damage within Eureka and the Baldesion Arsenal and does not otherwise change its stats or appearance.

Many of the Eureka Weapon names are shared with the Walk of Echoes upgrades for the Trials of the Magians weapons from Final Fantasy XI.
