Overview

Ancient Bell Snake (古钟蛇) is a Poison-type hidden spirit at Roco Kingdom: World's launch, captured through a stone-statue puzzle at Kingdom Prison. It evolves at Level 40 into Cold Sound Snake (寒音蛇), a Speed-focused PvP threat that stacks same-type power buffs from status moves.

How to Obtain

Ancient Bell Snake spawns at the Kingdom Prison lower-right area, near the Supervision Area Magic Source (监管区的魔力之源). The spawn is gated behind a stone-statue puzzle.

Travel to the statue area under the cliff in Kingdom Prison.
Throw a Poison-type spirit's skill at the statue. The weather changes in response to the poison trigger.
Ancient Bell Snake appears in the surrounding area. Capture it with a Gulu Ball.
The same statue also spawns Koola when a Water-type skill is used instead. The two are a paired capture chain.

Cold Sound Snake (Evolved Form)

Cold Sound Snake is the evolved form and the line's competitive piece. It is characterized by the highest Speed tier among Poison-type spirits and a species ability that rewards status-move usage.

Speed: 140 base, top tier.
Physical and Magic Defense: Both at 100 or higher.
Species Ability: Rattle Drum (拨浪鼓). Each status move cast increases same-type skill power by +10%. If the opponent is poisoned, Magic Attack gains an additional +40%.

Total base stat value is reported at 649 across sources. The full per-stat breakdown is not uniformly documented; confirm from the in-game dex before building a competitive set.

Recommended Skills (Cold Sound Snake)

Quick Move (快速移动): Speed-priority status skill that also serves as a Rattle Drum trigger.
Purple Drum Rhythm (紫鼓之律): Multi-hit damage move; scales with the Rattle Drum stack count.
Cold Snake Phantom (寒蛇幻影): Group heal plus weather summon; the weather effect complements the team's Poison coverage.

Competitive Notes

Offensive coverage: Poison hits Grass and Fairy supereffectively. Pairs well with Fighting teammates to cover Dark matchups.
Defensive weaknesses: Poison takes extra damage from Ground and Psychic. Keep a Flying or Dark partner to absorb those attacks.
Role: Status-stacking setup sweeper. Best used on teams that layer status moves across multiple turns before committing a damage skill.
