Verified notes
- Official announcement (2026-09-19, Four Kings update): "the sea serpent breaches under your units: pools open, then it rises and dives, stunning everything on both ends for 15s."
- Official counter rule: Demon vs Poseidon deals double damage, and each king's own faction places but stands down against him.
- Clearing the arena pays Kings Tokens (125 Easy / 250 Normal / 500 Horror, doubled by the 2x Coins pass) and can drop Poseidon's own urn (1% / 2% / 4% across the difficulties).
