Gilgamesh is a 5-star Lightning unit on the Path of Destruction who lives and dies by his 360-energy Ultimate and his stacking Interest resource. The right Light Cone feeds that loop directly, boosting his ATK, Energy Regeneration, and Ultimate damage so Enuma Elish fires harder and more often.
Quick answer: Equip I Am As You Behold, his signature Light Cone. If you do not own it, run A Thankless Coronation as a premium alternative or On the Fall of an Aeon from the Herta Store as the best free-to-play option.
Best Light Cones for Gilgamesh, ranked
Every pick below scales with ATK, CRIT, or Energy, which is exactly what Gilgamesh needs. The order reflects raw output, with rarity and how easy each cone is to obtain factored in.
| Light Cone | Rarity / Source | Why it works |
|---|---|---|
| I Am As You Behold | 5★ signature | ATK, Energy Regen, huge Ultimate DMG, teamwide CRIT DMG |
| A Thankless Coronation | 5★ (Saber’s signature) | Flat CRIT DMG plus ATK and energy on Ultimate |
| On the Fall of an Aeon | 5★ (Herta Store) | Stacking ATK and Weakness Break damage |
| A Trail of Bygone Blood | 4★ (Battle Pass) | Unconditional CRIT Rate, Skill and Ultimate DMG |
| Under the Blue Sky | 4★ | ATK plus CRIT Rate on enemy defeat |
I Am As You Behold: the best-in-slot pick
This is Gilgamesh’s tailor-made signature and his clear top choice. It raises his ATK by 18% and Energy Regeneration Rate by 10%, then increases Ultimate damage based on the Energy he consumes, up to a 72% boost at base refinement. Because his Ultimate drains such a large energy bar, that bonus is essentially maxed every cast.
It also carries team value. After Gilgamesh enters combat or uses his Ultimate, all allies gain increased CRIT DMG for three turns. That fits his role as a dual DPS and amplifier, especially alongside Saber. All of the numbers scale up with Superimposition, so extra copies from the banner sharpen every part of the effect.
Premium 5-star alternative: A Thankless Coronation
A Thankless Coronation is Saber’s signature, but its energy-based design lines up neatly with Gilgamesh’s high energy ceiling. It grants a flat 36% CRIT DMG at base, and using an Ultimate gives an 80% ATK boost for two turns while regenerating 10% of his maximum Energy.
The ATK and CRIT DMG combine into a strong damage swing, and the energy refund helps keep his expensive Ultimate online. If you already own it from Saber’s banner, it is the closest thing to his signature without pulling a second exclusive.
Best free-to-play option: On the Fall of an Aeon
On the Fall of an Aeon is the go-to free 5-star for Destruction carries, and Gilgamesh uses it well. You can buy and refine it to Superimposition 5 from the Herta Store, so no pulls are required.
At maximum refinement, each of his attacks stacks a 16% ATK increase, up to four times, and those stacks hold for the rest of the battle. Breaking an enemy’s Weakness then adds a 24% damage bonus for two turns. Since Gilgamesh attacks frequently, the stacks build fast and stay up, making this a reliable pick when you lack a signature cone.
4-star options: A Trail of Bygone Blood and Under the Blue Sky
If you have neither a 5-star signature nor On the Fall of an Aeon, two 4-star cones cover the gap. A Trail of Bygone Blood boosts CRIT Rate, Skill DMG, and Ultimate DMG with no conditions attached, which is exactly the stat spread Gilgamesh wants. The catch is that it comes from the Battle Pass, so not every player can grab it.
Under the Blue Sky is the widely available fallback. At Superimposition 5 it grants 32% ATK, and defeating an enemy adds 24% CRIT Rate for three turns. Note that once you own On the Fall of an Aeon, there is little reason to drop down to a 4-star cone.
What to prioritize when choosing a cone
Gilgamesh already pulls a lot of CRIT DMG from his own kit, since each point of Interest raises his CRIT DMG by 25% for up to six stacks. That means his cones are most valuable when they deliver ATK, CRIT Rate, and Ultimate-focused multipliers rather than more CRIT DMG on top.
- Prioritize cones that boost Ultimate damage, since Enuma Elish is his main output.
- Energy Regeneration is unusually useful because of his large Ultimate cost, though a support battery can cover it.
- Do not chase pure CRIT DMG cones when a balanced ATK or CRIT Rate option is available.
Match the cone to what you own. Pull for I Am As You Behold if you want his full ceiling, lean on A Thankless Coronation if it is already in your inventory, and fall back to On the Fall of an Aeon for a strong build that costs nothing.
