Thousandthorn Helm(千棘盔)
Worn Form
Water Poison Final Form Regional Form
Though short, the spines are thicker and sturdier, giving them higher breathing efficiency than other Thousand-Spine Helmets—they can rapidly intake and expel oxygen from seawater, maintaining stable breathing even in turbid waters. Some individuals have poison sacs at their spine tips, but the toxin is weaker, usually only causing slight numbness to those who touch them.

Poison Sustain Build
Playstyle
At the start, Corrosive Acid stacks 2 layers of Poison to activate the trait; then Brine Bath activates energy cost reduction; afterwards use Spring for damage (with Poison attached) or Venom Infiltration to consume Poison for damage depending on the situation. Venom Infiltration has extremely low energy cost when enemy Poison layers are high, enabling sustained pressure. Brine Bath's defensive response effect can trigger stronger reduction when predicting enemy attacks.
Why this set works
With "Dissolution Spread" trait as core, rapidly stack poison via "Corrosive Acid," reduce global energy cost with "Salt Bath," use "Springing Water" as main Water-type damage with poison attached, and "Venom Infiltration" as efficient poison consumption and renewal. Four skills form a complete poison stacking-consumption-energy management loop with stable rhythm and sustained output.
Corrosive Acid
Why pick this skill
Core Poison Stacking skill. Directly applies 2 stacks of Poison to the enemy, quickly meeting the Poison stacking requirement for Trait "Dissolution Diffusion", while also providing resources for follow-up Poison-consuming skills (Venom Seepage, Corruption).
Spring
Why pick this skill
Core Water-type damage. Combined with trait "Dissolution Spread", carrying 1 Poison-type skill allows Spring Gush to apply 1 Poison layer. 60 energy cost can be reduced further with Brine Bath, and power +10 per -1 energy cost, highly compatible with energy cost reduction system.
Venom Infiltration
Why pick this skill
Core poison consumption output skill, lower Energy cost with more enemy Poison stacks (can drop to very low cost), while adding 1 Poison stack to enemy per use, forming a positive cycle of "stack Poison → consume Poison → stack Poison again".
Saltwater Bath
Why pick this skill
Key support skill: Provides global -2 Energy Cost (-3 when responding to Defense), significantly reducing actual Energy Cost of Geyser and Venom Infiltration, making Geyser's power bonus easier to trigger and Venom Infiltration easier to reduce to low Energy Cost.
Quick Poison Stack Control Flow
Playstyle
At the start, Plague Breath (0 energy) + Corrosive Acid to quickly stack 3 layers of Poison; on turn 3, Corruption reduces enemy's dual attack by 90%, then Venom Infiltration sustains output at extremely low energy cost. Corruption's attack reduction allows Millenary Helm to safely hold the field, not fearing physical breakthrough even with low Physical Defense.
Why this set works
A support-oriented control build centered on rapid Poison stacking + Corruption field control. Quickly max Poison stacks with Plague Breath + Corrosive Acid, then Corruption drastically cuts enemy ATK/MAG, finishing with Poison Infiltration for low-cost sustained damage. Ideal for weakening high-ATK enemies before counterattacking.
Plague Breath
Why pick this skill
0 Energy Cost fast poison method. Only 1 Poison stack but no cost, usable on turn 1 or when conserving energy. Combines with Corrosive Acid or other methods for rapid poison stacking.
Corrosive Acid
Why pick this skill
Core Poison Stacking skill. Provides 2 stacks of Poison. Combined with Plague Breath, can stack to 3 Poison layers within 2 turns, quickly activating follow-up Poison-consuming skills.
Venom Infiltration
Why pick this skill
Core poison consumption burst skill, Energy cost greatly reduced when enemy has high Poison stacks (drops to 117 at 3 Poison stacks, even lower with Salt Bath), while adding 1 Poison stack per use, a high-frequency output method.
Corruption
Why pick this skill
Key field control skill that reduces dual attack based on enemy Poison stacks (-30% per stack, -90% at 3 stacks). Using this after completing Poison stacking can greatly weaken enemy output capability, creating a safe damage environment for allies.
Notes
- Thousand Thorn Helm (Worn Form) is a Water/Poison dual-type special attacker. Trait 'Dissolving Spread' requires carrying Poison skills for Water skills to apply poison effects. Base stats: 100 MATK, 107 MDEF, 105 SPD, making it a mid-speed special attacker. 74 DEF is low and needs attention. Skill pool built around poison system with stack poison, drain poison, transfer poison mechanics, plus Water damage output and energy management tools.
- Key mechanics: 1) Poison-type skills trigger trait, making Water-type skills inflict Poison; 2) 'Corruption' reduces dual attack based on Poison stacks; 3) 'Venom Infiltration' consumes Poison to reduce energy cost and stack Poison; 4) 'Poison Mist' converts enemy buffs to Poison; 5) 'Salt Bath' provides global energy cost reduction.
- With sufficient skill pool depth and tight mechanic synergy, two builds with different tempos are constructed around the poison system.
