WaterPoisonFinal FormBoss Form
There are a few reports of sightings of such a bizarre spirit. It seems that even a glance can cause a stinging sensation. Its body is larger than a bird's, and its spikes are sharper than blades. The insect body itself can no longer be found. They no longer need to worry about protecting themselves; instead, other creatures need to worry about them.

Recommended Skill Sets
Poison Rush Build
Playstyle
At the start, Brine Bath reduces energy cost; Corrosive Acid stacks Poison to activate; Venom Infiltration reaps; Water Splash fills energy.
Why this set works
Use Salt Bath to reduce energy costs. Corrosive Acid for quick poison stacking startup. Venom Infiltration as core output utilizing low-cost high-power cleanup. Water Splash supplements damage and recovers energy. Trait Dissolving Corrosion allows Water Splash to also stack poison, forming a complete poison system.
Venom Infiltration
Why pick this skill
Core burst skill, the more Poison stacks on enemy, the lower the Energy cost (can reach 0 Energy minimum), and each use additionally inflicts 1 Poison stack, forming a virtuous cycle of stacking Poison - reducing cost - stacking more Poison.
Saltwater Bath
Why pick this skill
Core support skill that provides -2 energy cost to all skills (-3 when responding to defense), greatly reducing the energy threshold for high-cost skills like Venom Infiltration. Energy guarantee for sustained output.
Corrosive Acid
Why pick this skill
Trait Dissolution requires Poison-type skills to trigger Poison from Water-type skills. Corrosive Acid is a skill that reliably stacks 2 layers of Poison, creating the activation condition for Venom Infiltration.
Water Splash
Why pick this skill
Low-cost Water-type skill that can inflict Poison on attack when combined with its trait, while self-recovering 1 energy to alleviate energy pressure, serving as a filler skill during Venom Infiltration downtime.
Poison Weakening Consumption Build
Playstyle
Plague Breath applies permanent poison, Corruption weakens enemy damage output, Venom Infiltration finds opportunities to deal damage, Foam Mirage handles fatal blows from super effective types.
Why this set works
Plague Breath provides permanent poison stacks, Corruption utilizes poison stacks to weaken enemy offenses, Venom Infiltration for damage, Bubble Phantom for survival. Compensates for low physical defense through weakening enemy output + self-preservation.
Venom Infiltration
Why pick this skill
Core burst skill, relies on Poison stacks to reduce Energy cost. This is the main damage output method of this build.
Plague Breath
Why pick this skill
0 Energy cost to apply 1 stack of Poison Mark (permanent Poison) on the enemy. Provides stable stack source for Venom Infiltration without disrupting turn output rhythm.
Corruption
Why pick this skill
The more poison layers on the enemy, the greater the dual attack reduction ( -30% per layer). Combined with multi-layer poison, can significantly weaken enemy output capability and improve self-survival.
Bubble Phantom
Why pick this skill
Reaction skill, 80% damage reduction + hit escape. Addresses Thousand Thorn Sea Needle's weakness to Electric/Earth/Phantom/Evil, providing critical survival measure
Spring Burst Build
Playstyle
Brine Bath reduces energy cost at battle start, Corrosive Acid stacks poison to initiate, Poison Mist targets buffed enemies or supplements poison, Spring as stable high-power damage to clean up.
Why this set works
Brine Bath reduces Spring's energy cost while increasing damage, Corrosive Acid initiates poison, Poison Mist targets buffers and supplements poison, Spring serves as main damage output. Compared to Venom Infiltration style, Spring has more stable power after energy cost reduction and doesn't rely on existing enemy poison stacks.
Spring
Why pick this skill
Core damage skill. Combined with Brine Bath's Energy reduction, can be cast at low Energy cost. Power increases as Energy cost decreases (+10 Power per -1 Energy).
Saltwater Bath
Why pick this skill
Key support: Energy Cost reduction has direct damage increase effect on Geyser while benefiting other skills—the operational core of the entire strategy.
Corrosive Acid
Why pick this skill
Essential for triggering trait; 2 stacks of Poison to start, creating a Poison environment for subsequent moves.
Poison Mist
Why pick this skill
Converts enemy buffs into Poison, highly effective against buff-reliant enemy creatures while supplementing Poison stack count
Notes
- Thousand Thorn Sea Needle's core mechanic revolves around poison stack count. Trait Dissolving Corrosion combined with Poison skills allows Water skills to apply poison effects.
- Base stats of Magic Attack 85 / Magic Defense 133 / Speed 100 lean toward special attacker + special wall, but Physical Defense 94 is low—watch out for physical attacks.
- Skill pool focuses on Poison + Water-type Magic damage, lacking buffing means. Relies on Poison stacking and Energy cost control for sustained output.
- Venom Infiltration is the core burst skill. Combined with multi-layer Poison, achieves low-cost high output.
- Brine Bath is a key energy cost support skill that can greatly reduce the entire team's skill energy consumption.
