11 Overview
22  
33 Hollow 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.

1010 Night 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.

1717 Scavenge (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.

34+ 
3335 Offensive 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.

3537 Tips
3638  
3739 Farm 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.
