Roundeye Spider(圆眼蜘蛛)
Bug Phase I Original Form
Young Roundeye Spiders are not very capable of weaving webs to hunt, mostly feeding on grass and tree fruits. Their compound eyes have an extremely wide range and rapid information acquisition—even with only one eye, a Roundeye Spider gathers information over 100 times faster than the Roco race.

Extreme speed poison stacking burst build
Playstyle
Frequently use 0-energy skills to trigger traits and quickly stack Poison layers, when enemy Poison layers are high, use Venom Infiltration's energy cost reduction for near-free magic burst, while Poison Feeds Poison provides Magic Attack boost to strengthen output.
Why this set works
Maximize ‘Venom Gland’ by using three zero-cost moves to frequently apply 4-layer Poison stacks; complement with ‘Poison Needle’ for efficient poisoning; finish with ‘Toxic Permeation’, which reduces energy cost per Poison layer for low-cost, high-burst output. ‘Poison Counterattack’ grants Sp. Atk boost, and ‘Poison Ambush’ doubles Poison layer count—completing a full ‘Poison Stack → Burst’ loop.
Poison Needle
Why pick this skill
Core Poison Stacking skill. 20 Energy cost, after triggering Trait "Poison Gland" actually applies 4 stacks of Poison to the enemy plus 1 stack to self, stacking 5 Poison layers in one use—the most efficient Poison stacking method.
Fight Poison with Poison
Why pick this skill
0 Energy Cost skill. Triggers trait to apply 4 stacks of Poison to the enemy. Also increases own Magic Attack based on enemy's Poison stacks, dealing considerable damage after stacking Poison.
Kick Them When They're Down
Why pick this skill
0 Energy Cost skill. Triggers trait to apply 4 stacks of Poison to the enemy. Doubles enemy's debuff stacks, allowing Poison to rapidly stack to high levels when combined.
Venom Infiltration
Why pick this skill
High-cost Magic skill, but -1 Energy per Poison stack on enemy. Nearly 0 Energy at max stacks. Adds 1 Poison on hit. Combines burst with Poison maintenance.
Energy Storage Sustained Support Build
Playstyle
Build high dual-attack stats with "Stockpile" as core, use 3 zero-Energy skills to simultaneously trigger trait Poison stacking and attack bonuses, "Cocoon" ensures survival and team lifesteal, "Kick Them When Down" accelerates Poison stacks, finally use "Venom Infiltration" for buffed burst damage, positioned toward sustained combat and team support.
Why this set works
Three 0-cost skills perfectly trigger the full dual attack bonus (+150%) from 'Storage', while each 0-cost skill triggers the 'Poison Gland' trait to stack Poison; 'Cocoon' provides sustain and team support, 'Kick Them When They're Down' accelerates poison stacking, and finally 'Venom Infiltration' benefits from high magic attack bonuses and low-cost burst, balancing damage, sustain, and team contribution.
Cocoon
Why pick this skill
0 Energy Cost skill. Triggers trait to apply 4 stacks of Poison to the enemy. Also provides 20% HP recovery and 10% team lifesteal devotion effect, enhancing sustainability.
Storage
Why pick this skill
0 Energy Cost skill. Triggers trait to apply 4 stacks of Poison to the enemy. When equipped with multiple 0 Energy Cost skills, provides high both Attack stats bonus (3 zero-cost skills in this set, +150% both Attack), strengthening damage output foundation.
Kick Them When They're Down
Why pick this skill
0 Energy Cost skill. Triggers trait to apply 4 stacks of Poison to the enemy. Doubles enemy's debuff stacks, rapidly pushing Poison stacks to high levels.
Venom Infiltration
Why pick this skill
High-cost Magic skill. Relies on enemy Poison stacks to reduce Energy. Low-cost after stacking Poison. Combines burst with Poison maintenance.
Physical Counter Burst Build
Playstyle
Rapidly stacks poison with Pitfall Toxin and boosts Physical Attack with Power Boost; Bite delivers consistent physical damage; reserves Bug Strike for response-triggered burst—dealing double damage and ignoring resistance—ideal for predictive counterplay.
Why this set works
Dual 0-cost skills trigger trait Poison stacking with separate functions (double Poison, Physical Attack boost). 'Bite' serves as stable physical output, 'Bug Strike' provides burst in Counter state. This set abandons the magic route for pure physical output, but note 'Bug Strike's high 90 cost requires proper Counter timing.
Kick Them When They're Down
Why pick this skill
0 Energy Cost skill. Triggers trait to apply 4 stacks of Poison to the enemy. Doubles enemy's debuff stacks, key to rapid Poison stacking.
Power Boost
Why pick this skill
0 Energy Cost skill. Triggers trait to apply 4 stacks of Poison to the enemy. Provides 100% Physical Attack bonus, strengthening physical damage output.
Bite
Why pick this skill
40 Energy Cost Physical skill, 1 combo, affected by Devotion but this set has no Devotion source so no negative effect; serves as main Physical output method
Bug Strike
Why pick this skill
High energy cost Physical skill, power doubles and ignores resistance when countering; as Physical burst finisher, can deal high damage when countering.
Notes
- Round-Eyed Spider is a Tier I creature with low base stats (305), but its Speed of 66 is decent for its tier. Its trait "Poison Gland" applies 4 stacks of Poison to the enemy when using skills with ≤1 Energy cost—this is its core mechanic.
- Bug-type is super effective against Grass, Illusion, and Dark types, and is weak to Wing and Fire types. Pay attention to type disadvantages.
- Skill pool focuses on Poison stacking and Physical/Magic damage, lacking strong control and survival skills. Positioned as Poison attrition with burst support.
- Extremely rich 0 Energy Cost skill pool (Cocoon, Poison Feeds on Poison, Kick 'Em When They're Down, Storage, Power Boost), highly synergizes with trait "Poison Gland". Core of build strategy.
