Their heads have almost no vision, mainly relying on their mouths to sense airflow for direction, occasionally charging wildly across the surface. When roaring, the bell-shaped flowers in their mouths vibrate, emitting waves of bell sounds. They communicate with each other through these sounds.

Recommended Skill Sets

Dual Shield Stall

Playstyle

Slow tank that uses reaction skills to reduce damage and counter enemy combos, with Salt Gathering for sustained HP and Energy recovery, using Trample when energy is sufficient

Why this set works

Utilize dual counter skills (Muddy Skin + Burrow) to cover different damage types, Salt Gathering provides sustain and scaling, Trample as finishing move. Stable playstyle, suitable for attrition battles.

Salt Gathering

Why pick this skill

Trample

Why pick this skill

High-power Physical attack (130 Energy cost). Used after accumulating Energy and marks with Salt Gathering as the primary finishing move.

Sandstorm Control Build

Playstyle

Open with Sandstorm to change environment, adjust Enzyme Concentration to heal when attacked, use Salt Accumulation for sustained field presence, Rock Vein Collapse for fixed low-cost damage output.

Salt Gathering

Why pick this skill

Core sustain skill, urgently needed HP recovery when entering at low HP, Salt Accumulation's growth also makes it stronger as battle progresses.

Enzyme Concentration Adjustment

80% damage reduction response skill. Restores 20% HP on successful response; compared to Slime Skin, focuses more on healing than suppressing enemy combos, suitable for pure survival playstyle.

Sand Surge

Extreme Counter Build

Playstyle

Completely relies on response mechanism combat. Chooses different response skills based on enemy actions: Earth Spike to interrupt key skills, Branch Draw for large healing, Mud Skin to suppress combo output.

Why this set works

Three Counter skills form a complete counter chain: Mud Skin reduces combos, Earth Spike interrupts, Branch Draw heals, Salt Gathering provides basic sustain. Maximizes the Counter mechanic to its fullest.

Salt Gathering

Physical damage skill with Counter state: on successful counter, additionally interrupts the countered skill, possessing powerful counter-interruption capability.

Branch Out

Why pick this skill

Physical damage skill with Counter state: on successful counter, recover 50% HP and 5 energy—massive healing combined with counter mechanics forms a perfect loop.

Notes
  • Eel Tail Beast's trait 'Lily of the Valley Evening Bell' causes it to lose half its current HP upon first entry, meaning it starts at low health and needs quick healing or low-HP mechanics.
  • Base stats: Physical Defense 138 is high, Magic Defense 113 is moderate, both offenses 91 are low, Speed 65 is extremely slow. Positioned as a slow tank/attrition pet.
  • There are multiple Counter skills in the skill pool (Mud Skin, Burrow, Enzyme Adjustment, Earth Spike, Branch Whip), suitable for counter-attacking and attrition battles
  • Salt Gathering is the only stable self-healing method, and can grow permanently, almost mandatory
  • With extremely slow speed, securing initiative is nearly impossible, thus relying on counter mechanics and weather/field control to fight.
