Well, it takes 420k Jewels per ONE P2W Eidolon. And you're only looking at 4/11 chance for a 140% one. 1.1m Jewels per P2W. So that's 1/192.5 rerolls? And THEN you intend to land on one good SSR as well, for which the odds are minimal.
Honestly, you were probably lucky to get what you wanted this soon.
Also, reminder of the 30 buck mini-Miracle Ticket for new players which will net you Gaia. While Gaia is a pure defensive Hime, she does an amazing job at some content. Now, should you sink 80 bucks into a game you've only just started is up to you.
(And if you haven't bought Cu yet, Azazel Awakened is stronger than Cu Awakened. But the thing is, Azazel pre-Awakening is trash, and after Awakening boosts your team, which won't be top tier until much later anyway so... Cu isn't a BAD choice either.)
