Sea Monster (Legends of Runeterra)

“	"Sailors speak in hushed tones of dark days to come; when the seas churn and boil, and unspeakable horrors rise from the waves."
	— On 3Lure of the Depths

Sea Monster is a group unique to a small set of Bilgewater, and even smaller set of Shadow Isles followers. The main distinction they have in-game is their universal usage of the Deep keyword, and their synergy with 7Nautilus.

The Sea Monster cards are the horrors that roam the seas of Runeterra, particularly the depths around the Serpent Isles and the oceans surrounding the Shadow Isles. Many appear to be corrupted by the Black Mist or The Void, and many of the monsters are large parts of Bilgewater's traditions.

The Sea Monsters are thematically associated with the fear of the impending death they bring, and of the unknown or unknowable.

Strategy

Decks with Sea Monsters often use Toss to reach Deep faster. Once they reach Deep, they have access to very powerful, cheap units.
- For the early game, these decks can use Lifesteal, Drains and controlling spells to survive while working towards the depths.
- 7Nautilus (Level 2) and 3Lure of the Depths can be used to reduce the cost of Sea Monsters. Nautilus' cost reduction along with his high stats can on its own win games.
- 5Abyssal Eye or 8Terror of the Tides are good at closing out games, usually leaving the enemy unable to block.
- 6Devourer of the Depths can obliterate key cards on the opponent's board, even champions. It is especially strong if it is buffed, for example if the player is already deep.
4Maokai is a champion often used in conjunction with 7Nautilus in Sea Monster decks.

Trivia

7Nautilus level up condition may be to go deep, but he is not classified as Sea Monster and does not have the keyword, yet he does receive a large stat bonus for being Deep.
