Note: Compared to the other Legendary Dragons, the Shellfire dragon does not require the completion of a Collection to be placed on Berk. Instead, it can be unlocked instantly, once all requirements have been reached.
Dragons Offered in Shellfire Collections:
There are no Resource Collections in the Shellfire Collections, so every Collection is guaranteed to be for a Grim Dragon.
Occasionally, Polished Amber is rewarded along with the collection item found in each Shellfire search.
Every Collection for a Grim Dragon consists of any random combination of 6 of the following Collectibles:
The needed amount is only dependent on the Collectible itself and does not change for other Shellfire Collections.
