Fenrir's inventory acts as a fridge.

Fun fact! If you place Fenrir by a direwolf, the direwolfs eyes turn all smokey icy like.

I am not sure if this is due to a glitch in my game, but karate chop the upwards voting system if you see this too.

It’s inventory acts like a refrigerator

Fenrir boost- all direwolfs in range take less damage and deal more damage-eye color change indicates this buff

The Fenrir refrigerator effect does not work on Primal Crystal.

Very useful for raising wyverns and drakes because fenrir's inventory acts like a preserving bin/fridge making the milk or venom last 2 days in its inventory

They are a mobile fridge. They make milk and venom last for 2 days in it's inventory

Only one person in the fight will get a cryo pod with a Fenrir in it once the boss dies, and the level depends on which difficulty fight you pick. (On official)

Gamma: 150

Beta: 190

Alpha: 225

Fenrir close to direwolves cause the direwolves' eyes to glow, and gives them a buff which reduces incoming damage by ~12.5% and increases damage output by ~25%. This buff can stack with mate boost, pack bonus, howl, and yuti roar.
