Recommended Skill Sets

Mark Conversion Control Build

Playstyle

Open with Poison Spore to quickly stack 5 Poison layers, converted to 2-3 Mark layers via end-of-turn Trait; next turn choose Plague Breath to supplement Marks or Venom Infiltration for direct output based on Energy; mid-game use Infection to finish low-HP targets and convert remaining Poison to Marks, continuously pressuring enemy HP while accumulating Mark layers

Why this set works

A Mark flow built around the trait "Etching." Toxic Spores fast poison stacking → trait converts to marks → Plague Breath supplements marks → Venom Infiltration low-cost output → Infection harvests and converts, forming a complete Poison-type control and output chain.

Toxic Spore

Why pick this skill

Core Poison stacking skill. 0 Energy cost to directly inflict 5 Poison stacks. Combined with trait for quick conversion to marks. The key to startup tempo.

Plague Breath

Why pick this skill

0 Energy Cost: Grants 1 Poison Mark stack. Combines with Trait to form a mark stacking system, creating output conditions for Venom Infiltration and Infection.

Venom Infiltration

Why pick this skill

Core damage skill with energy cost decreasing with more enemy Poison stacks (minimum 0), and applies Poison for virtuous cycle. Core M.ATK-oriented skill.

Infection

Why pick this skill

Execute + conversion skill. When defeating a target, converts Poison into marks. Combined with early Poison stacking to form a harvest rhythm, 85 energy cost requires reasonable planning.

Buff Burst Build

Playstyle

At the start, use Deadly Poison to stack poison (8 layers when countering defense), immediately gaining high Magic Attack bonus from Fighting Poison with Poison and enemy dual attack reduction from Corruption. Next turn, use Warm-up Exercise to gain Combo +3 then Energy Cannon for 2+3=5 combo burst, or Venom Infiltration for sustained output. Maintain high buff state through 0-energy skill cycle, suppressing enemy output while strengthening self.

Why this set works

Utilize Severe Poison for rapid poison stacking, simultaneously triggering Poison vs Poison's Magic Attack buff and Corruption's enemy debuff, forming an integrated offense-defense buff system; Energy Cannon as burst finisher, Warm-Up can be swapped for other utility skills based on situation

Fight Poison with Poison

Why pick this skill

0 Energy Cost, enemy Poison stacks provide Magic Attack buffs (up to several times multiplier), the core enhancement method for Special Attack output.

Severe Poison

Why pick this skill

0 Energy Cost fast poison startup, providing stack foundation for Poison Feeds on Poison and Corruption. 8 Poison stacks on Defend response has extremely high value.

Corruption

Why pick this skill

0 Energy: Debuff skill—enemy Poison stacks provide dual attack reduction (up to several times), serving both offensive support and survival functions.

Energy Cannon

Why pick this skill

High-cost Magic damage skill. 2-hit combo with Warm-Up can deal high burst. Damage becomes considerable with Poison for Poison bonus.

Notes

Qiuka is a high-speed Poison-type special attacker. Its Speed of 125 is the highest base stat, while its Magic Attack of 83 is decent but its Physical Attack of 93 is higher, giving it mixed attacker potential.
The trait "Etching" converts Poison into Poison Mark, allowing rapid mark stacking when paired with Plague Breath.
Poison Mark mechanics not explicitly explained, but speculated to be stronger sustained damage or negative status
Skill pool lacks speed buffing means, relies on priority advantage.
Energy management key: Multiple 0-cost skills (Fight Poison with Poison, Corruption, Toxic Spores, Plague Breath, Lethal Poison, Warm-up) enable flexible rotation.
