I Am As You BeholdI Am As You Behold is Gilgamesh's signature damage and Energy option for his high-cost Ultimate.
A Thankless CoronationA Thankless Coronation supports his repeated Skill damage in the transformed state.
Thus Burns the DawnThus Burns the Dawn supplies a strong general Destruction damage profile without requiring Saber-specific ownership.
On the Fall of an AeonOn the Fall of an Aeon builds ATK through repeated Skills and rewards a personal Weakness Break.
When to use it : Gilgamesh must personally break Weakness for its damage bonus.
A Secret VowA Secret Vow is the retained non-Battle-Pass four-star fallback for a damage-focused Destruction build.
A permanent four-star Warp cone, not a Battle Pass reward.
When to use it : The lower-HP damage bonus applies only while Gilgamesh is below the cone threshold.
Relics
Genius of Brilliant Stars is the specialist best when its Quantum and DEF-ignore clauses are actually active.
When to use it : Use against Quantum-weak enemies, especially when the team can add DEF reduction.
The Ashblazing Grand Duke only pays off when Gilgamesh himself performs the multi-hit Follow-Up that builds its ATK stacks.
When to use it : Use it when Saber triggers Gilgamesh's own Joint Follow-Up ATK, or Mortenax Blade E2 makes Gilgamesh's own Ultimate count as a Follow-Up ATK.
Scholar Lost in Erudition is the stable general set for Skill and Ultimate damage outside those specialist conditions.
Planar Ornaments
Cosmic Life Sciences Institute is the source-backed general planar choice for Gilgamesh's personal output.
Izumo Gensei and Takama Divine Realm adds ATK and a same-Path CRIT condition tailored to the Saber pairing.
When to use it : Run Saber beside Gilgamesh so a same-Path Destruction teammate activates Izumo's 12% CRIT Rate at battle entry.
Inert Salsotto keeps its CRIT and Ultimate/Follow-Up bonuses relevant to the Joint-attack plan.
When to use it : Use it when Ultimate and Follow-Up damage are the primary share of the rotation.
Team lineup
Saber and Gilgamesh unlock their exact Joint Follow-Up, Mortenax Blade adds broad vulnerability and frequent attacks, and Huohuo sustains while accelerating both high-Energy Ultimates.
When to use it : Use Mortenax Blade's Zone before the paired Ultimates, let Huohuo refill both expensive carries and never spend Saber's Ultimate before the Joint Follow-Up applies its 240% multiplier.

Trace priority
- Talent

- Skill
- Basic ATK
Gilgamesh observes ally actions until his Skill-only state becomes permanent, batteries his 360-Energy Enuma Elish from ally Ultimates and forms a Joint Follow-Up ATK with Saber.
How to play it
- 1Open with Enkidu when possible for 3 Interest, then let other allies act until Gilgamesh has gained 10 Interest and permanently enters Interest Piqued.
- 2After transformation, use Gate of Babylon every turn to keep King's Acknowledgement active; each teammate Ultimate adds King's Burden, 2 Interest and fixed Energy equal to 30% of its cost.
- 3With Saber, count their attacks to 8. The Joint Follow-Up grants Gilgamesh 3 Interest, restores Saber's fixed 120 Energy and makes her next Ultimate deal 240% of its original damage; cast Enuma Elish inside the team's full debuff window.
Sources and methodology
Editorial recommendations are written from released game data, then cross-checked against specialist calculations. They are not copied from a single tier list.
Review method
Character kits, equipment and conditions reviewed against released Version 4.6 data. Retained ten Interest, Gate of Babylon Skill and the eight-attack Saber pair; fixed ally-Ultimate gains remain separate from ERR. Gate of Babylon is a Skill, not an enhanced Basic: Heretic 134 misses the main channel and does not buff Enuma Elish. Actor 133 has no ally target. The Elation cones 21066/23055/23064, Hunt cone 22008 and Remembrance cone 23063 do not match this character’s Path. Kit and condition review against the 4.6 snapshot; no new damage or full-rotation simulation and no recalculated optimal ranking. This review includes no new damage simulation; historical community-analysis consultation dates are preserved. Methodological baseline from the previous dossier (review 4.4, reference calculations 4.4): Prydwen and Icy Veins were read independently for Gilgamesh's released HSR Version 4.4 build, never for the source franchise, then checked against the exact local snapshot. The maxed E0 Trace-level-15 model distinguishes temporary 10%-per-Interest combat SPD from sheet SPD, caps CRIT at 100%, and caps Hero's Hauteur at six gained-Interest stacks. It counts the Saber Joint Follow-Up only after eight Gilgamesh-or-Saber attacks, then applies the released fixed 120 Energy and 240%-of-original next Ultimate multiplier to Saber. Cosmic Life Sciences Institute reaches its exact 32% cap because Gilgamesh's 360 Max Energy exceeds 200 by 160. Official 4.4 notes and the immutable snapshot establish the same release baseline, so no synthetic delta is claimed.

Independent E0 HSR recommendations. The CRIT target stops at 100% in combat, and the base-SPD build does not count temporary Interest SPD as sheet SPD.
