His effectiveness is tied to his “Amuse Me to the Fullest” talent and his synergy with Saber, which allows for devastating joint follow-up attacks. He demands careful management of Energy, Interest stacks, and turn sequencing.* **For Meta Enthusiasts:** His joint-attack potential—boasting 200% of his ATK and 300% of Saber’s—suggests elite DPS potential, particularly at higher Eidolon levels.* **For Collectors:** Being a crossover exclusive, his availability will be extremely limited. This release window is likely your only chance to add him to your roster.* **For F2P Players:** His performance is tightly linked to Saber. Without her, you forfeit a significant portion of his total damage output. Weigh this heavily before investing your Stellar Jades.### Leaked Ability Summary (Beta Data)* **Basic Attack (Halfhearted Blow):** Single-target Lightning DMG (50% ATK).* **Skill (Gate of Babylon):** Grants 3 turns of “King’s Acknowledgement,” providing 15% DEF ignore. Deals 140% ATK (primary) and 70% ATK (adjacent) Lightning DMG.* **Ultimate (Enuma Elish):** Deals 200% ATK (AoE) followed by 10 hits of 50% ATK to random targets.* **Technique (Enkidu):** Freezes enemies in place for 10 seconds. Engaging combat here initiates with 200% ATK Lightning DMG to all enemies and grants 3 Interest stacks.### Ascension and Trace RequirementsTo fully maximize Gilgamesh, you will need to prioritize farming **Thunder Strum** (weekly boss drops) and **Squirming Core** (enemy drops). Upgrading his Traces will also demand massive amounts of Credits (approx. 3 million) and specific rare materials like **Omnicolor Fool’s Own**. ### Eidolon Breakdown* **E1 (He Who Saw the Deep):** Spreads DEF ignore to allies; increases ATK and Energy refund.* **E2 (Wisdom That Encompassed All):** Starts battles with bonus stacks; significantly boosts Skill multipliers.* **E6 (Soul That Bore Friendship):** The ultimate power spike, providing Resistance Penetration for the team and massive CRIT DMG scaling for his Ultimate.### Final ThoughtsGilgamesh is a synergy-dependent powerhouse whose utility is greatly enhanced by his connection to Saber. Because this is a special crossover event, you have time to prepare. Begin gathering your materials today to ensure he is ready for battle the moment he arrives.
