Griffon will help you get Skyscale as you scramble around Dragonfall for eggs and sick skyscales collections. Additionally, Griffon will also make the Dragonfall Meta easier so you can get all the bosses after Kralk. Doing the meta is a part of the process to get skyscale since it helps you get the 250 currency of that map.
It's probably not worth getting it just for that, but in the later parts of the collection there will be a bit of back and forth to do stuff in the Sunspear Sanctuary, and this allows you to teleport there. Speaking of which, in the Sanctuary you'll have to play a game of hide and seek with your skyscale eventually.

Reviving players and NPCs in WvW also counts. You can do this at the same time you are doing the Skyscale of Blood achievement. You can do this by having a party member (if you have one) fall from the wall next to where the priestess is located. You can then revive them repeatedly to complete the task.
