Seal has 400 health and spawns in the Deep North.
It takes extra damage from fire; spirit does nothing to it at all. Blunt, slash and pierce land at full damage, so that is what to bring.
Of everything craftable, 
Frostfire Crossbow, 
Thunderblood Crossbow and 
Frostfire Sledge put the most damage through what it resists.
It always drops 
Seal Pelt and 
Seal Blubber.
Seal is a passive Deep North shore animal with 400 health, a run speed of 3 and no attack at all in its data, which makes it one of the few things in the biome that is purely a resource. It is weak to fire and immune to spirit. Each kill gives 2 to 3 Seal Pelt and 2 to 3 Seal Blubber, with the 
Seal Trophy at 10 percent. Seal pelt is the hide the 
Moose Saddle is built from, so clearing a stretch of coast comes before riding a 
moose.
Nothing to fight, just something to harvest, and the drops are better than the difficulty suggests. Every seal gives 2 to 3 Seal Pelt and 2 to 3 Seal Blubber with a 10 percent trophy on top. The pelt is in the Hood and Trousers of the Vanguard, the 
Cape of the Caller, the 
Ember Charge and the Moose Saddle; the blubber goes into 
Seal Meat Soup and unbaked poteitr.
| Where | Roll | Group | Conditions |
|---|---|---|---|
| Deep North | 50% every 100 s, max 5 near you | 1 to 2 | altitude -2 to 5 m · up to ★★ |
Each 64 m zone keeps its own timer per entry and rolls the chance once per interval while loaded; a zone never loaded before rolls the moment you arrive. The spawn lands 40 to 80 m from a player, never inside a base unless noted, and "max near you" counts the loaded area around that zone. Dungeon and camp spawners are separate and not counted here.
With devcommands enabled, this spawns Seal in front of you. The third number is the level: 3 spawns a 2-star.
