Hollow Skull(空空颅)

Ghost Phase I Original Form

Easily found in dilapidated empty houses at night. Though weak in strength, it has a terrifying appearance and intimidates other sprites to protect itself. It barely relies on sight, instead sensing heat to determine the location and distance of creatures.

Recommended Skill Sets

Energy Control Finisher Build

Playstyle

Use Soul Hook to control enemy energy, creating conditions for Backstab's 20x damage. Quick Movement ensures first strike priority, with Spectral Burst as the regular output method.

Why this set works

With [Backstab's] 20x finisher as core, stable energy control trigger via [Soul Hook], [Spectral Burst] provides regular damage, [Quick Move] solves speed disadvantage. Strategy: Can lead or switch in, prioritize Quick Move for speed advantage or Soul Hook for energy control, choose Spectral Burst for pressure or Backstab finisher based on enemy energy.

Backstrike

Why pick this skill

Core execution skill; deals 20x damage to enemies with 0 Energy. This creature's most threatening damage source. Combined with Soul Hook for Energy control, can be triggered reliably.

Soul Snare

Why pick this skill

Steals 3 enemy energy, directly creating trigger conditions for Backstab while disrupting enemy skill cycles, extremely cost-efficient at 0 energy cost.

Spectral Burst

Why pick this skill

This type's highest power output skill (140 Energy cost), used for regular output and finishing off, compensates for damage shortfall when Backstab doesn't trigger.

Quick Move

Why pick this skill

Gains +80 Speed, +160 when responding to Defense. Compensates for Speed shortcomings to ensure first move. Highly effective against Defense-reliant enemies.

Switch Prediction Burst

Playstyle

Predict or force enemy switch, use Spirit Light Combo doubling and Mockery dual buffs to stack trait bonuses, achieving single-turn maximum burst.

Why this set works

An enhancement burst system built around enemy swaps. [Flash of Insight] + [Mock] simultaneously trigger hit doubling, Magic Attack +90%, Speed +70, and trait Magic Attack +20% when predicting swaps, resulting in extremely high single-turn burst. [Spectral Burst] as regular damage, [Soul Grasp] provides energy control disruption. Play concept: Force enemy swaps through pressure, or actively predict swaps to use Flash of Insight/Mock, maximizing synergy benefits.

Spirit Light

Why pick this skill

3-hit magic damage skill, if enemy swaps pet this turn hits double to 6 hits, forms perfect synergy with trait [Scavenge]'s swap buff.

Mockery

Why pick this skill

Gains +90% Magic Attack. If enemy switches creatures, additionally gains +70 Speed. Combines with Spirit Light to form double benefits from switch prediction, greatly boosting damage and Speed.

Spectral Burst

Why pick this skill

This type's high-power output skill, considerable damage after Magic Attack buff, stable output when Divine Light doesn't trigger.

Soul Snare

Why pick this skill

Steals 3 energy to disrupt enemies while creating energy advantage for subsequent Backstab or other skills, highly versatile.

Notes
  • Hollow Skull is a Ghost-type special attacker with high 37 Sp.Atk base stat and only 7 Atk, should completely abandon physical attack skills.
  • The trait [Scavenge] provides +20% Magic Attack buff when the enemy gathers energy or switches creatures, suiting late entry or forced-switch tactics.
  • Speed 48 is somewhat low, must rely on 【Quick Move】 or 【Taunt】 speed boost effects to contest speed
  • 【Backstab】's 20x damage is core execution method, but needs to cooperate with Energy control skills to trigger
  • Shallow skill pool, only high-power elemental skills are 【Ghost Burst】【Sonic Boom】, with high energy costs
  • 【Spirit Light】combo doubles when enemy swaps pet, forms synergy with Trait, suitable for predicting pet swap
  • 【Soul Hook】,【Spirit Descent】, and【Sunbathing】provide utility, but【Spirit Descent】has no direct damage and requires pairing with damage skills.
