Release5.9

Helical Contraption is Vill-V's S-rank QUA-type Fire battlesuit: she summons Loud Armaments (a Gatling gun, a heavy cannon and a mortar), then rides her tank, Special Weapon: No. 9, in burst mode. She was more of a Quantum-enemy specialist than a general Fire DPS, her best scores came against QUA bosses, and she has no Astral Ring. Marisa Impact advises against pulling for her; she only has a place in Part 1 Fire teams today.

Weapons

Tower of the Past: Silk Ladder BiS
S
Best in slot (BBS, Marisa Impact): big damage, a piercing burst-mode weapon active and extra damage to Locked enemies. Craftable in the Foundry.
Helical Contraption's PRI-ARM cannon: Locked enemies take more Fire DMG, entering or switching Weapon Mode calls cluster-bomb support, and in burst mode the weapon active becomes a piercing, gathering shot.
Tower of the Past
A
The base form keeps the Weapon Mode support fire; available in the Exchange House.
Helical Contraption's signature cannon: the same Locked state and Weapon Mode support fire as its PRI-ARM, without the extra burst-mode damage passive.
Briareus EX

BBS universal pick: +25% Elemental DMG on a QUA wielder and a DEF-shredding time-slow field.

Guide

How to play

Weapon Mode

  • Tap ATK or ULT to summon her Loud Armaments and enter Weapon Mode (60% less damage taken). Hold ATK to fire: the Revolving Gatling: Applause shoots continuously, the Heavy Cannon: Exclamation fires big shells. Tap Weapon to switch between them, which also triggers her Ultimate Evasion (mortar and Burn Zone).
  • Attacking fills Weapon Heat (max 200); at full heat she enters Climax Approaching, where every shot hits much harder and she regains SP and HP.
  • With Tower of the Past, entering or switching Weapon Mode calls cluster-bomb support (7s CD).

Burst mode: Special Weapon: No. 9

  • Hold ULT (above 50 SP) to build the tank and enter burst mode: 500% ATK to all enemies and QUA enemies are Collapsed once. Tap ATK for cannon shots, hold EVA to ram enemies.
  • At full Chariot Heat, hold ATK for Interlude Salute (1,000% ATK and an Ultimate Evasion). Tap ULT to self-destruct into enemies (900% + 70% per second spent in burst mode) under Time-frozen Domain.
  • Burst mode drains SP (5/s, then 15/s after 5s) and lasts at most 16s. Going back into Weapon Mode within 5s restores 150 Weapon Heat.

Marisa Impact's loop: hold ATK in Weapon Mode for a while to trigger your buffs, Ultimate into burst mode, hold ATK until the second Interlude Salute, then Ultimate again to self-destruct, and go back to Weapon Mode until burst mode is available again.

Strengths

  • Very strong against QUA-type enemies: Collapse on Ultimate and extra Fire DMG against QUA and Collapsed QUA enemies.
  • Tanky: 60% damage reduction in Weapon Mode and 70% in burst mode.
  • Her gear is easy to get: the Carlo Collodi set is craftable, and G4 Little Joys is Marisa Impact's long-term alternative.
  • Big leader skill for Fire teams (+20% Total and Fire DMG at SS3).

Weaknesses

  • Outdated: no Astral Ring, not used in current Abyss or Memorial Arena teams; Marisa Impact advises against pulling for her.
  • Her buffs target QUA enemies rather than Fire content in general.
  • She cannot use Sparkle's double Ultimate, because her Ultimate ends burst mode (Marisa Impact).
  • Burst mode drains SP quickly and needs careful timing.
