11Overview2233Hollow Skull (空空颅) is a pure Ghost-type spirit exclusive to Season 1 of Roco Kingdom: World. Lore notes highlight that it relies on heat sensing rather than vision, which matches its fragile but intimidating appearance. The wild spirit has a fixed nighttime spawn on the mountain ridge above the factory in the eastern region of the Kaluoxi'a Continent.4455Full Evolution Chain6677DexNameChineseEvolves At#327Hollow Skull空空颅Base form#328Night Sleeper夜宿颅Level 30 AND successfully use the Soul Hook (勾魂) skill 3 times in battle. Misses, dodges, and interrupts do not count.#329Night Owl夜枭Level 50, plus 3 Ghost Cores (幽灵核心) and 5 Night Dust (暗夜之尘) as evolution materials.88Night Owl (夜枭) Details991010Night Owl is the final stage of the Hollow Skull line and the form most competitive players aim for. It is characterized by very high HP relative to the Ghost archetype and a species ability that stacks magic damage during extended fights.11111212StatValueHP253Magic Attack74Magic Defense941313The remaining three base stats (Physical Attack, Physical Defense, Speed) have not been confirmed in detail from reliable sources and are omitted here.14141515Species Ability: Scavenge16161717Scavenge (搜刮) triggers every time the opponent switches spirits or casts a skill. On trigger, Night Owl's Magic Attack increases by 20%. The buff can stack, which punishes swap-heavy and high-APM enemy teams.18181919Recommended Skills (Night Owl)20202121Control (操控): Dark status move that forces the opponent to skip a turn; also deals Dark damage.Sneak Attack (偷袭): High hit-rate Magic Attack damage.Sonic Boom (音爆): Physical damage plus a disturbance effect.Pierce (穿膛): Percentage-based damage that ignores both Physical and Magic Defense.Ghost Burst (幽灵爆发): 140-power Magic Attack nuke; doubles when the Scavenge stacks have reached a threshold.22222323Ghost Core and Night Dust Sourcing24242525Ghost Core (幽灵核心): Drops from wild Ghost-type encounters at Abandoned Empty House (废弃空屋), East District Factory Back Mountain (东区工厂后山), and Black Water Cliff (黑水崖).Night Dust (暗夜之尘): Exchanged at the spirit evolution shop for in-game gold.26262727How to Obtain28282929Fixed wild spawn: Nighttime only, mountain ridge above the East District Factory on the Kaluoxi'a Continent. Requires high-tier Gulu Balls.Season 1 Nightmare Shackles: Ghost and Ghost sanctuary fruit pair using Dream Walker (梦游) and Little Ghost Mask (小灵面) for Nightmare Shackles rotations.Season shop exchange: 50 Light-Gather Tokens buys a Precious Chance-Encounter Spirit Egg at the Box Research Laboratory vendor.30303131Competitive Notes32323333Offensive coverage: Ghost hits Light, Ghost, and Phantom supereffectively. Night Owl is a natural check to Light-type legendaries.Defensive weaknesses: Ghost takes extra damage from Ghost and Light. Mirror matches become speed races; carry a faster Ghost teammate if you expect the matchup.Role: Consumption and stacking; strongest against swap-heavy teams where Scavenge stacks accumulate quickly.34343535Tips36363737Farm Ghost Cores while leveling Hollow Skull toward 30. Wild Ghost spirits drop Cores on a rolling probability, so materials stockpile on the path to the evolution trigger.Hit the Soul Hook trigger count reliably by pairing Hollow Skull with a teammate that applies slow or stun. Soul Hook cannot miss when the target is already locked down.Save Night Dust purchases for the final Level 50 push. Mid-game gold tends to run tight during the first evolution track.Use Night Owl (not the earlier stages) in PvP. Scavenge is the line's payoff ability and only activates on the final form.38383939See Also40404141Spirits - full rosterSeason 1: Dark Night Collecting Light - season contextNightmare Shackles - Season 1 capture mechanicElement Types - Ghost matchups
