Recommended Skill Sets

Speed Attack Cleanup Build

Playstyle

Utilize speed advantage for preemptive damage. Flying Sever as low-cost cleanup to trigger trait, Insect Strike for burst kills during response states, Cocoon for sustain, and Equivalent Exchange to counter enemy burst skills. Fast overall tempo, excels at snowballing.

Why this set works

Maximize Demon Red Diamond’s high Physical Attack and Speed: use Fly Cut (low-cost) for rapid cleanup, triggering its ability’s snowball effect; Bug Strike serves as the main burst; Bug Cocoon ensures sustainability; Equivalent Exchange guarantees survivability. A well-rounded playstyle suited for most matchups.

Flying Sever

Why pick this skill

Core finisher skill. Only 20 Energy Cost, combined with Trait can trigger 5 random Devotions after defeating enemy, quickly accumulating team advantage. The +20 power Devotion effect also boosts subsequent output.

Bug Strike

Why pick this skill

Core damage skill. Power doubles when responding and ignores type resistance. Has miraculous effects against super-effective types or high-defense targets. Demon Red Diamond's strongest burst method.

Cocoon

Why pick this skill

Sustain and team support skill. Recovers 20% HP to ensure survival, 10% Life Drain Tribute enhances team sustained combat capability, extremely valuable in endgame or attrition battles.

Equivalent Exchange

Why pick this skill

A powerful counter-attack skill. 90% damage reduction provides extreme survival capability; 50% lifesteal when countering attacks enables counter-healing—a key survival tool against high-burst enemies

Burst Suppression Build

Playstyle

Open with Power Devour to weaken enemies and strengthen self, use Extreme Tear to attempt instant kill on key targets at full HP, follow with Flying Sever to trigger Snowball Trait on success, use Cocoon to recover when attack is lowered or at low HP. Aggressive tempo, pursuing rapid enemy reduction.

Why this set works

Limit Tear serves as the opening high burst, Flying Cut executes to trigger the trait, Power Devour buffs self and weakens enemies, Cocoon provides sustain. Suitable for quickly establishing advantages, but requires careful HP management.

Extreme Rend

Why pick this skill

High-power Physical attack (135 Power). The main drawback is -50% to both offenses after use when HP is above 50%, but extremely powerful as an opening burst or one-shot skill at full or high HP.

Flying Sever

Why pick this skill

Core finisher skill. Low Energy Cost combined with Extreme Tear priority OHKO can immediately trigger Trait to provide 5 Devotions for entire team, forming continuous pressure.

Power Devour

Why pick this skill

Team support skill: enemy all skill power -20, self all skill power +20, this trade-off significantly improves team survival and self damage output, massive advantage in direct confrontation.

Cocoon

Why pick this skill

Sustain skill. Recovers 20% HP and grants team Life Drain Tribute, recovers state after Extreme Rip attack reduction or at low HP, ensuring sustained combat capability.

Armor Break Attrition Build

Playstyle

Priority Keen Eye significantly reduces enemy dual defenses, followed by Bug Strike burst output, Bat provides stable lifesteal sustain, Equivalent Exchange counters enemy key skill retaliation. Relatively steady tempo, excels against tank-type enemies.

Why this set works

Centered around Keen Eye's extreme defense reduction, Insect Strike for burst damage, Bat for stable lifesteal sustain, Equivalent Exchange to handle counters. Suitable against high-defense targets or prolonged battles, with strong team support capability.

Bat

Why pick this skill

Lifesteal skill. 100% of damage dealt converted to HP recovery. Demon Red Diamond's most stable sustain method; combined with high Physical Attack, recovery amount is substantial.

Keen Eyes

Why pick this skill

Defense reduction support skill. Extreme -120% enemy physical/magic defense reduction, creates excellent conditions for subsequent physical output, can also assist teammates

Bug Strike

Why pick this skill

Core damage skill. After Sharp Gaze defense reduction, Bug Strike's power doubling effect can deal devastating damage. The resistance-ignoring trait can also overcome type disadvantages.

Equivalent Exchange

Why pick this skill

Counter-attack response skill. Damage reduction + lifesteal combination allows Demon Red Diamond to survive and heal when enemy counters, forming dual lifesteal security with Bat.

Notes
  • Demon Red Diamond has extremely high Physical Attack (147) and excellent Speed (115), but low defenses, especially Magic Defense (74). Its trait [Invigorating Bug Heart] provides 5 random Devotions to the entire team after actively defeating an enemy, giving it strong snowballing cleanup potential. Bug+Dark typing is weak to Flying, Fire, Light, Bug, and Cute, so entry timing matters. Its skill pool focuses on physical damage with lifesteal, defense reduction, power reduction, and healing support, suiting it as a fast cleanup attacker or sustained damage dealer
