Shellfire Collections are Collections that once all items are gathered, you will receive a Grim Dragon for each completed collection.
The Shellfire Collections for Grim Dragon will only become available after the Shellfire dragon has been unlocked.
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.
Needed Collectibles[]
Every Collection for a Grim Dragon consists of any random combination of 6 of the following Collectibles:

Note:
The needed amount is only dependent on the Collectible itself and does not change for other Shellfire Collections.
Just like the Drago's Bewilderbeast Collections and the Purple Death Collections, the Shellfire Collections also only have one randomly needed Collectible from Explorations.
