Tangtang

endgame sub dps

supportsub_dpsdebuffaoe

Tangtang earns SS tier because she brings a rare combination of strong AoE Cryo damage, repeated Arts Susceptibility debuffs, and a wide-area Ultimate that pauses enemies to create a safe damage window. This flexibility lets her slot into many teams as a plug-in debuffer with meaningful personal damage.

This endgame build turns Tangtang into a strong sub-DPS and debuffer. The Brigand's Calling weapon and Bonekrusha gear set both feed her Whirlpool-to-Waterspout sequence, letting her apply Arts Susceptibility frequently while dealing respectable Cryo damage. The LYNX Slab off-piece maximizes her main stats, and the overall rotation lets her contribute meaningful damage during her own skill rotations while also amplifying her team's Arts damage.

Insights

Core Mechanics

RIVER, TO ME! creates a Whirlpool that is consumed by IMA WAVERIDAAH! to form Waterspouts; only when 2 or more Waterspouts form does the Arts Susceptibility debuff apply.
Her Ultimate DA CHIEF SEES YOU! locks down enemies in an area; a dive attack ends it early for a stronger wave and converts nearby Whirlpools into boosted Waterspouts.
Waterspouts apply Cryo Infliction and deal Cryo damage over time, while multiple Waterspouts add an Arts DMG Taken debuff to enemies in range.

Scaling

Her damage and debuff strength scale with Agility, Strength, and Battle Skill DMG, so builds that stack these stats also amplify her support.
Early game she relies on weapon and gear stat bonuses for personal damage; late game the Bonekrusha combo payoff makes her sub-DPS contribution much larger.
Team support value scales indirectly with how often multiple Waterspouts can be created, which depends on enemy grouping and Whirlpool generation.

Team Role

Tangtang is a Cryo Caster who functions as a debuffer-sub-DPS hybrid. She prefers teams that can group enemies so her Battle Skill creates multiple Waterspouts, extending Arts Susceptibility to the whole pack. Her Ultimate buys precious time for slow, high-damage carries such as Yvonne or Last Rite. She is especially strong in Arts damage rotations where the Arts Susceptibility debuff increases everyone's burst. In single-target fights, she needs her Combo Skill Whirlpool first or she loses the debuff application; with grouped mobs she can skip this prep. Her flexibility means she is often used as a plug-in slot in many comps rather than the centerpiece.

Explanation

Brigand's Calling is the best-in-slot weapon because it boosts Tangtang's Detonate and Attack/Agility stats while applying an Arts susceptibility-like debuff to enemies, increasing party-wide Arts damage.

The Bonekrusha gear set rewards casting Combo Skill before Battle Skill, which matches Tangtang's intended Whirlpool setup and Waterspout conversion very well.

Home Longing is a solid alternative for personal Cryo damage but lacks the team debuff, and Opus: The Living or Long Road are weaker budget picks that should only be used when Brigand's Calling is unavailable.

Notes

The Bonekrusha set converts a combo skill cast into a big bonus on the next battle skill, so the Whirlpool into Waterspout rotation gets a large payoff.
Use LYNX Slab as the off-piece because its main attribute percent gain outperforms the extra Battle Skill DMG from a second Bonekrusha Mask.
Do not chase a third piece for the set; the Battle Skill DMG bonus saturates and the off-piece provides more overall value.
Brigand's Calling also applies an Arts DMG Taken debuff, making the whole team's Arts burst stronger, not just Tangtang's own damage.
