I got the 100% egg boost and Prospero to just before Vanguard.
My remaining problem is I’m having to sit on my hands to keep from blowing a bunch of rubies or chests on Sylphen. Am I crazy? That little monster seems special. I’m several breeds away from Hauheset and not sure I will be able to fly her effectively, but couldn’t Sylph be a ton of fun, educational, and a decent setup / cleanup dragon for tough war or atlas attacks? If they can get the chains working reliably. I got orange sylph on my alt and then that phone died.
