Light Cone
I Am As You BeholdI Am As You Behold is the unique best for Gilgamesh's complete role: ATK, Energy Regeneration Rate, up to 72% Ultimate DMG and a non-stacking 24% team CRIT DMG buff.
When to use it : Enter combat or use Enuma Elish at least once every three turns to preserve King's Entertainment; the 72% Ultimate cap uses all 360 Energy.
On the Fall of an AeonOn the Fall of an Aeon S5 builds 64% ATK through Gilgamesh's repeated Skill and adds 24% DMG after he personally breaks a Weakness, making it the strongest permanent free baseline.
This five-star Destruction cone is permanently redeemable and superimposable through Herta's Store without a limited Light Cone Warp.
Under the Blue SkyUnder the Blue Sky supplies ATK and grants CRIT Rate after the wearer defeats an enemy.
When to use it : Use when the character can maintain the CRIT Rate buff by defeating enemies regularly.
Relics
Scholar Lost in Erudition is the defensible general best: CRIT Rate plus unconditional Skill and Ultimate DMG supports both main attacks without Genius's enemy-Weakness condition.
When to use it : Use Enuma Elish before the next Skill so Scholar's post-Ultimate Skill bonus is not wasted; this general recommendation does not assume Quantum Weakness.
Two-piece Messenger Traversing Hackerspace plus two-piece Guard of Wuthering Snow is a transition mix: Increases SPD by 6%. Reduces DMG taken by 8%.
It reuses strong pieces from two sets while a complete four-piece configuration with equivalent main stats and substats is still being farmed.
Planar Ornaments
Cosmic Life Sciences Institute is the unique general best planar because it grants the full unconditional 32% DMG to Skill, Ultimate and Joint Follow-Up alike.
When to use it : Gilgamesh's released 360 Max Energy is 160 above the 200 threshold, reaching the ornament's 32% DMG cap exactly.
Broken Keel is a ranked alternative with this two-piece effect: Increases the wearer's Effect RES by 10%. When the wearer's Effect RES is at 30% or higher, all allies' CRIT DMG increases by 10%.
When to use it : Reach 30% Effect RES to activate the teamwide CRIT DMG bonus.
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
- Ultimate
- 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
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.
