Stormfly

Stormfly is Astrid's Dragon.

Stormfly is a Unique Deadly Nadder dragon of the Tracker Class.

Acquisition
Stormfly is unlocked for purchase in the shop after rebuilding Astrid's House.

During the first day the price is discounted, so it is recommended that players ensure they have enough runes before rebuilding Astrid's House.

Stormfly can be purchased from the shop for 225 Runes (90 for 24 hours after completing Astrid's House)

Purchasing Stormfly completes a quest that provides a reward of 300 Runes.

Dragon Design
Unfortunately with premium dragons like this one there is no egg. Once you make the purchase it will go directly into your village / Hangar.
