Seahelm Bug(海盔虫)
WaterPoisonPhase IRegional Form
When motionless, it resembles an unremarkable reef, making it hard to tell if it is alive. It moves slowly in a benthic manner, with activity level directly tied to food availability—moving only slightly when food is scarce. Photosensitive cells distributed between its spines make it highly sensitive to strong light, often instinctively hiding in shadows.

Poison Stack Attrition Build
Playstyle
At the start, use Plague Breath + Corrosive Acid to quickly stack poison. When 3+ layers, activate Corruption to greatly weaken enemy output. Then use low-cost Venom Infiltration for sustained output and poison renewal. Utilize poison layer snowball to suppress opponent.
Why this set works
Maximize ‘Dissolving Diffusion’ synergy: use two Poison-stacking moves to rapidly accumulate layers; Corrosion provides survivability; Toxic Permeation serves as the core damage dealer—scaling stronger with each Poison layer—completing a full ‘Poison Stack → Weaken → Burst’ loop.
Plague Breath
Why pick this skill
Core Poison stacking skill. 0 Energy cost to directly inflict 1 Poison stack on enemy, providing base stacks for all subsequent Poison synergy skills, while also triggering trait "Dissolution Spread" count.
Corrosive Acid
Why pick this skill
Core Poison Stacking skill. 35 Energy cost for 2 stacks of Poison + Magic damage, rapidly stacking Poison layers. Works with Trait to allow Water-type skills to apply Poison.
Venom Infiltration
Why pick this skill
Core damage skill with 120 base Energy cost, but reduces Energy cost by 1 and adds 1 Poison stack for each Poison stack on the enemy. After stacking Poison, Energy cost can drop extremely low while dealing more Poison over time, forming double synergy with the Trait.
Corruption
Why pick this skill
Key support skill: 0 Energy Cost to reduce both enemy ATK stats based on their Poison stacks (-30% per stack). 3 Poison stacks reduce both ATK by 90%, greatly improving survivability and securing output turns for slow creatures.
Energy Burst Build
Playstyle
At the start, Water Storage + Brine Bath sets up energy reduction environment; on turn 2, release 0-energy high-power Spring for burst; Bubble Illusion is used to respond to enemy key skills or for survival; suppress opponent rhythm through high-frequency low-cost skills.
Why this set works
Abandon the poison stacking system in favor of energy cost management and burst damage. Utilize the dual energy reduction mechanics of Water Storage + Salt Bath to maximize Geyser's power, with Foam Phantom compensating for survivability. Suitable for situations requiring quick battle resolution or facing high-burst opponents.
Water Storage
Why pick this skill
0 Energy startup technique, reduces next skill energy cost by 6, works with Brine Bath to achieve 0 or near-0 energy cost release of Spring, is the core of burst setup
Saltwater Bath
Why pick this skill
0 Energy cost passive buff, permanent -2 Energy cost for all skills, -3 when defending. Pairs with Water Storage to minimize Gushing Spring's Energy cost, while increasing frequency of skills like Venom Infiltration.
Spring
Why pick this skill
Core burst skill, base 60 Energy cost, +10 Power for each Energy reduced. Combined with Water Storage + Salt Bath, it can be reduced to 0 Energy and reach 110 Power. This is the highest cost-effective choice for Water-type damage output, while also triggering the trait to inflict Poison.
Bubble Phantom
Why pick this skill
0-cost counter-skill granting 80% damage reduction and automatic disengagement when responding to an attack—vital survivability tool for slow, fragile Pokémon, preventing OHKOs from Electric- or Ground-type moves.
Anti-Buff Specialized Stream
Playstyle
Against opponents with buff enhancements, prioritize Poison Mist to clear their buffs and convert to poison, Corrosive Acid to supplement stacks, Venom Infiltration for output, Bubble Illusion to respond to enemy burst skills or save key turns, specifically countering buff-stacking strategies.
Why this set works
Specialized solution against buff-dependent opponents. Poison Fog provides unique buff clear mechanism. Combined with traditional poison stacking components to form a "clear buffs - stack poison - output" tactical chain. Bubble Phantom ensures survival for slow startup.
Poison Mist
Why pick this skill
0 Energy Cost strategic skill. Converts all enemy buffs to Poison. Highly effective against buff-reliant opponents. Also provides poison stacks to trigger follow-up synergies.
Corrosive Acid
Why pick this skill
Core Poison Stacking skill. 35 Energy cost stably provides 2 stacks of Poison + Magic damage, the top choice for quickly replenishing stacks after Poison Mist.
Venom Infiltration
Why pick this skill
Core damage skill. Relies on Poison stacks to reduce energy cost and extend Poison. After Poison Mist Conversion + Corrosive Acid, energy cost can typically drop below 110 while maintaining high Poison stacks.
Bubble Phantom
Why pick this skill
0 Energy Cost survival skill. 80% damage reduction + retreat on response. Buys critical turns for deploying Poison Mist and stacking poison, avoiding first-move OHKO.
Notes
- Helmet Crab is a Stage I creature with low base stats (327), slow 60 Speed, with 59 Magic Attack as its only highlight, positioned as a stall/support Poison-type mage
- The trait "Dissolution Diffusion" requires carrying Poison-type skills to trigger Poison application on Water-type skills, so skill selection must balance Poison-type skill quantity with Water-type skill quality.
- Skill pool centers on Poison stacking + Water-type damage, lacking control and recovery. Relies on Poison stacks for prolonged battles.
- Weak to Electric, Earth, Fantasy, and Dark, watch for type disadvantage
