Normal Attack
Performs up to 6 consecutive shots with a bow.

Charged Attack
Performs a more precise Aimed Shot with increased DMG.
While aiming, the power of Hydro will accumulate on the arrowhead. An arrow fully charged with the torrent will deal Hydro DMG and apply the Riptide status.

Plunging Attack
Fires off a shower of arrows in mid-air before falling and striking the ground, dealing AoE DMG upon impact.
When Tartaglia is in Foul Legacy: Raging Tide’s Melee Stance, he cannot perform a plunging attack.

Riptide
Opponents affected by Riptide will suffer from AoE Hydro DMG effects when attacked by Tartaglia in various ways. DMG dealt in this way is considered Normal Attack DMG.
Riptide Flash: A fully-charged Aimed Shot that hits an opponent affected by Riptide deals consecutive bouts of AoE DMG. Can occur once every 0.7s.
Riptide Burst: Defeating an opponent affected by Riptide creates a Hydro burst that inflicts the Riptide status on nearby opponents hit.

Unleashes a set of weaponry made of pure water, dealing Hydro DMG to surrounding opponents and entering Melee Stance.
In this Stance, Tartaglia’s Normal and Charged Attacks are converted to Hydro DMG that cannot be overridden by any other elemental infusion and change as follows:

Normal Attack
Performs up to 6 consecutive Hydro strikes.

Charged Attack
Consumes a certain amount of Stamina to unleash a cross slash, dealing Hydro DMG.

Skill Combo:
– 2 NA + 1 CA (Optimal)
– 3 NA + 1 CA (Recommended)
– 5 NA + 1 CA (Recommended combo if using Rust or Thundering Pulse)
*NA = Normal Attack, CA = Charged Attack

Riptide Slash
Hitting an opponent affected by Riptide with a melee attack unleashes a Riptide Slash that deals AoE Hydro DMG. DMG dealt in this way is considered Elemental Skill DMG, and can only occur once every 1.5s.

After 30s, or when the ability is unleashed again, this skill will end. Tartaglia will return to his Ranged Stance and this ability will enter CD.
The longer Tartaglia stays in his Melee Stance, the longer the CD.
If the return to a ranged stance occurs automatically after 30s, the CD is even longer.

Maximum Duration: 30 seconds
Preemptive Cooldown: 6-36 seconds
Max Cooldown: 45 seconds

Optimal skill duration for [C0]: 7s, 9s or 12s.
Optimal skill duration for [C1]: 9s, 11s or 14s.

Performs different attacks based on what stance Tartaglia is in when casting.

Ranged Stance: Flash of Havoc
Swiftly fires a Hydro-imbued magic arrow, dealing AoE Hydro DMG and applying the Riptide status.
Returns a portion of its Energy Cost after use.

Melee Stance: Light of Obliteration
Performs a slash with a large AoE, dealing massive Hydro DMG to all surrounding opponents, which triggers Riptide Blast.

Cooldown: 15 seconds
Energy Cost: 60

Melee Stance Burst: Only to be used in situations where you need only 1 rotation to clear as the ER requirement to maintain burst uptime is quite high (170-190%), you’ll always want to start your rotations with Ranged Burst since it refunds energy to maintain your rotation well.

Riptide Blast
When the obliterating waters hit an opponent affected by Riptide, it clears their Riptide status and triggers a Hydro Explosion that deals AoE Hydro DMG.
DMG dealt in this way is considered Elemental Burst DMG.

1) Polar Star (ATK: 608 • Crit Rate: 33.1%)

[Refinement 1] Elemental Skill and Elemental Burst DMG increased by 12%. After a Normal Attack, Charged Attack, Elemental Skill or Elemental Burst hits an opponent, 1 stack of Ashen Nightstar will be gained for 12s. When 1/2/3/4 stacks of Ashen Nightstar are present, ATK is increased by 10/20/30/48%. The stack of Ashen Nightstar created by the Normal Attack, Charged Attack, Elemental Skill or Elemental Burst will be counted independently of the others.

Has varied performance depending on how many passive stacks you get. Getting 2-3 stacks at the start of your rotation can perform better than Thundering Pulse while getting no stacks can perform worse than Skyward Harp.
This only applies if you are Vaporizing Childe Burst together with Bennett. In teams without Bennett, Polar Star will always perform better than the other options.
3 stacks can be achieved by doing Skill + 1 Normal + 1 Charged Attack before setting up your Vaporize Burst. If your Skill is still on cooldown, a fully Charged Aimed shot against a Riptide affected target, OR a Ranged Normal + quick Aimed shot gives 2 stacks (which can be followed by Skill for the 3rd stack).

2) Thundering Pulse (ATK: 608 • Crit DMG: 66.2%)

[Refinement 1] Increases ATK by 20% and grants the might of the Thunder Emblem. At stack levels 1/2/3, the Thunder Emblem increases Normal Attack DMG by 12/24/40%. The character will obtain 1 stack of Thunder Emblem in each of the following scenarios: Normal Attack deals DMG (stack lasts 5s), casting Elemental Skill (stack lasts 10s); Energy is less than 100% (stack disappears when Energy is full). Each stack’s duration is calculated independently.

Slightly better than Skyward Harp depending on rotations – the more time you spend doing Normal Attacks, the more it pulls ahead over Skyward Harp, but it’s not recommended to extend your Childe’s melee rotation for this.

3) Skyward Harp (ATK: 674 • Crit Rate: 22.1%)

[Refinement 1] Increases CRIT DMG by 20%. Hits have a 60% chance to inflict a small AoE attack, dealing 125% Physical ATK DMG. Can only occur once every 4s.

4) Amos’ Bow (ATK: 608 • ATK: 49.6%)

[Refinement 1] Increases Normal Attack and Charged Attack DMG by 12%. After a Normal or Charged Attack is fired, DMG dealt increases by a further 8% every 0.1 seconds the arrow is in the air for up to 5 times.

5) The Viridescent Hunt (ATK: 510 • Crit Rate: 27.6%)

[Refinement 1] Upon hit, Normal and Aimed Shot Attacks have a 50% chance to generate a Cyclone, which will continuously attract surrounding opponents, dealing 40% of ATK as DMG to these opponents every 0.5s for 4s. This effect can only occur once every 14s.

Offers a valuable passive that helps a lot in grouping enemies, which can offer a ton of damage from Riptide.

6) Blackcliff Warbow (ATK: 565 • Crit DMG: 36.8%)

[Refinement 5] After defeating an opponent, ATK is increased by 24% for 30s. This effect has a maximum of 3 stacks, and the duration of each stack is independent of the others.

Due to the inconsistency of gaining stacks, falls off compared to other weapons at higher refinements.

7) Mouun’s Moon (ATK: 565 • ATK: 27.6%)

[Refinement 1] For every point of the entire party’s combined maximum Energy capacity, the Elemental Burst DMG of the character equipping this weapon is increased by 0.12%. A maximum of 40% increased Elemental Burst DMG can be achieved this way.

8) Rust (ATK: 510 • ATK: 41.3%)

[Refinement 5] Increases Normal Attack DMG by 80% but decreases Charged Attack DMG by 10%.

9) Slingshot (ATK: 354 • Crit Rate: 31.2%)

[Refinement 5] If a Normal or Charged Attack hits a target within 0.3s of being fired, increases DMG by 60%. Otherwise, decreases DMG by 10%.
