Cog is only available in the CN version of the game currently. We translated Cog skills ourselves, as such, there's a chance of localization errors. We will add the official translations as soon as they will be released. Please contact us directly to report any errors.

Active Skill

Pure Soundscape

Damage, Anti-Air

Lv. 1

Command CD: 12s

Uses: 5

Throws javelins at the target area, which explode to deal Water DMG equal to {0} Final ATK in a 250m area and deal Water DMG equal to 300% Final ATK to enemies along their path. Leaves 1 [Syncopation] at the target area. Each time [Pure Soundscape] is cast, Cog’s Auto Skill CD Recovery SPD increases by 40%, stacking up to 3 times. ([Syncopation]: When created, also creates a small Water Zone. A set number can be depleted to cast Active Skill [Fixed Track].)

Active Skill

Fixed Track

Damage, Barrier, Anti-Air, Barrier PEN

Lv. 1

Command CD: 1s

Uses: ∞

Auto Skill: CD 10s. Throws a javelin at the target, dealing Water DMG equal to {0} Final ATK, exploding to deal Water DMG equal to {1} Final ATK in a 200m area, and leaving 1 [Syncopation]. Active Skill: Depletes 4 on-field [Syncopation] to create a [Fixed Track] zone in the target area for 10s. When creating a [Fixed Track] zone, Cog deals Water DMG equal to {0} Final ATK to enemies in the area and leaves a javelin on each of the four corners to form a High Strength Barrier (breaking the Barrier does not affect the [Fixed Track] zone’s duration). While the [Fixed Track] zone is active, whenever an Echomancer triggers [Vaporized], [Electroconduct], and [Frozen] reactions, Cog deals an instance of Water DMG equal to {2} Final ATK to enemies in the zone and reduces the targets’ DR by 50% (this effect is considered [Armor Melt]) for 10s. This effect can be triggered once every 5s. Multiple [Fixed Track] zones may exist on field at the same time. All zones disappear after Cog leaves the field.

Seed Skill

Dual Synthesizer

Damage, Debuff, Anti-Air, Barrier Break

Lv. 1

Charge Time: 45s

Summons 2 groups of javelins in a 600m area that destroy all enemy Barriers, knock down all Airborne units for 8s, and deal Water DMG equal to {0} Final ATK. Throws a final javelin at the center that deals Water DMG equal to {1} Final ATK in a 300m area. After this skill is cast, Cog’s next 2 Basic ATKs will create 1 [Syncopation] at the target.

Basic Skill

Carrier Wave Refrain

AoE, Anti-Air

Range: 1200

ATK Speed: 0.50/s

Throws a javelin at the target, dealing Water DMG equal to 180% Final ATK to enemies in a 200m-radius fan shape.

Combat Traits (Dupes)

When [Syncopation] reaches a certain number, can deplete [Syncopation] to actively cast [Fixed Track]. (When changing battle zones or when Cog leaves the field, all [Syncopation] disappears.)

Tier list comment

With virtually infinite skill uses and a fast skill cycling, Cog is a force to be reckoned with. Although she may not be as fast and straightforward as the likes of Lionel, she compensates with unique utility in the shape of square barriers. These can help control the battlefield while benefitting the whole team by reducing enemy DR by 50%.
