Si, a 6-star Cryo Supporter, arrived on October 15, 2026 with the Version 1.6 “Sanctuary of Ink” update. This guide collects the numbers published so far: her skills, the weapons ranked for her, the two main gear builds with their stats, stat priorities, example teams and her banner dates. Because she just launched, some sources are still preliminary, and those are marked.

Numbers Published By EndfieldHub
| Skill | Value |
|---|---|
| Fully Envisioned (combo) damage | 750% ATK, plus 100% per Infliction stack consumed, up to 4 stacks |
| Fully Envisioned cooldown | 15 seconds |
| Ultimate (Giant Ink Lung) damage | 500% |
| Ultimate energy cost | 80 |
| Energy returned per Ink Lung | 10 |
| Team Amp from each cast | Up to 36% Cryo and Heat Amp for 12 seconds |
| Yinglung’s Edge stacks | Maximum 3; three team battle skills between Ink Lungs fill them |
Mechanics
| Mechanic | Detail |
|---|---|
| Artful Intent | Records part of the damage dealt to the marked target and releases it as fixed AoE damage when the effect ends |
| Inksoul | A stationary target that redirects damage and effects to the linked enemy, useful against bosses that move or teleport |
| Ultimate return | Ink Lung energy return is the main limit on how often the Ultimate comes back |
Weapons
| Rank | Weapon | Notes |
|---|---|---|
| 1 | Jade Vessel (6-star Greatsword, signature) | Up to +44.8% ATK, up to +70% next combo damage after her Ultimate, up to +21% damage taken on the target she Immobilizes |
| 2 | Khravengger | Cryo DMG lines; its Strength line is only secondary for her |
| 3 | Long Heritage (6-star Greatsword) | Free from the 1.6 Protocol Pass; has a team Arts DMG line that is not in the damage calculator, and it is unconfirmed whether her Amp counts for it |
Other 5-star or 6-star Greatswords depend on their effects. One guide advises against heavy investment in multiple weapons before you settle on a team.

Ink Lung Damage Test (EndfieldHub)
| Build | Ink Lung damage |
|---|---|
| Type 50 Yinglung main build | 346,990 |
| Eternal Xiranite support build | 268,556 |
| Pre-1.6 Eternal Xiranite build | 159,842 |
Test conditions: Jade Vessel, skill rank 9, 3 Edge stacks, Amp off, level 90, talents maxed, Potential 0, no enemy DEF, crit-weighted expected damage.
Crafting Cost
| Item | Cost |
|---|---|
| Each 1.6 piece | 360 Wuling Stock Bills and 50 Pyrrolite Components |
| Main build (4 crafts, Beacon twice) | 1,440 Stock Bills and 200 Pyrrolite Components |
| Craft first | Channeling Gloves, since both builds use them |
Stat Priority
| Priority | EndfieldHub | TopUpLive (provisional) |
|---|---|---|
| 1 | Intellect | Intellect and compatible offensive stats |
| 2 | Strength | Damage bonuses that boost the combo skill |
| 3 | Combo Skill DMG | Cryo or Heat DMG and infliction value |
| 4 | Ultimate Gain Efficiency (Amp builds only) | Cooldown reduction, only if testing shows more combos per rotation |
TopUpLive also says to avoid stacking cooldown reduction or Arts Intensity until her final kit is tested. Pulser Labs gear is listed as lower priority because Solidification requirements may disrupt combo triggers.
Skill Upgrade Order
| Order | Skill | Source |
|---|---|---|
| 1 | Combo skill | TopUpLive (provisional) |
| 2 | Ultimate | TopUpLive |
| 3 | Battle skill | TopUpLive |
| 4 | Basic attack | TopUpLive |
LDShop lists skill priority and potentials as “TBD,” and EndfieldHub does not list potentials.
Example Teams
| Source | Team | Type |
|---|---|---|
| LDShop | Laevatain, Si, Camille, Arcane | Heat |
| LDShop | Laevatain, Si, Wulfgard, Akekuri | Heat |
| LDShop | Yvonne, Si, Arcane, Tangtang | Cryo |
| LDShop | Last Rite, Si, Arcane, Tangtang | Cryo |
| TopUpLive | Si, Xaihi, Arcane, Last Rite | Cryo, Si in slot 1 |
| TopUpLive | Laevatain (slot 1), Si, Wulfgard, Ardelia | Heat |
| TopUpLive | Yvonne, Si, Xaihi, Tangtang | Cryo; test slot 1 after release |
| EndfieldHub | Si in slot 1 with Xaihi and Arcane, or behind a slot 1 Laevatain | Cryo or Heat |
| EndfieldHub | Laevatain, Wulfgard, Akekuri (Eternal Xiranite build) | Heat |
EndfieldHub notes that Xaihi, Ardelia, Arcane and Gilberta usually run Eternal Xiranite, so the main Yinglung build is the default on most Cryo teams.
Rotation
No source gives a full rotation. The core loop described is:
- Apply infliction with the battle skill.
- Consume it to trigger the combo skill.
- Cast the Ultimate to shorten the first-slot operator’s combo cooldown.
Positioning in the team is the key variable, and three team battle skills between Ink Lungs fill the Yinglung’s Edge stacks.
Source Differences
| Point | Detail |
|---|---|
| Skill names | Brushwork Realm vs Brushstroke Realm; “No One Spoils the Fun” vs “Nobody Spoils the Fun” |
| Gear data | LDShop tables are placeholders; TopUpLive says its gear stats are unconfirmed and written before 1.6 went live; EndfieldHub gives final stats |
| Fourth team slot | Arcane, Last Rite, Tangtang, Akekuri and Ardelia each appear in different guides |
| Icy Veins | Its operator build page does not include Si |
