The Story
A long time ago (a long tamago?), seven dragons were born from a crystal full of desires. The name was “Sin Dragons”. With the godly “power of keys”, the heroes sealed the Tamago (base form of Sin Dragons) away.
Hundreds of years have passed since… Surprise, the Sin Dragons returned. At the same time, cute heroes are given the powers of the keys! With that, the new legend begins.

Misc.
Cate’s propaganda, lol:






































































































































































































































































































































Got my team builds all ready for whoever I roll. But yeah Ferule best girl.
As for the dragons, gotta stock up on a team of Greed for coin dungeons and lifetime dungeons.
Need me a bunch of Pride equips for the light and heal boards.
As for Golface and Golchaos, technically you can make all the keys, equip em and then reset the awakenings while they’re equipped and it’ll be like you’re just doing “assist invalid” dungeons instead of getting the detrimental HP minus and such.
Is there any use for Amlynea and Menuit? Those are the ones I rolled, and as far as I’m concerned, I haven’t got anything to use them well. (cries)
o wow tony, I never thought of that. It took me a second to realize what you mean. Yes you can do that, but that will cost you a downpy or w.e the alt form of that is. Downmandra lol
I’m willing to waste the sad Tamadra in order to not have my stats crippled.
But in that case why not just use the corresponding egg?
It’s all about the trade off in awakenings, namely chucking a stat you care little about for something you do.
It’s the sacred keys that have unique skills, the cursed ones are 1:1 with the sin dragon counterparts.
Just did it to get Gorchaos. The eggs I use for assists but just wanted to treat the challenge more like an assists invalid as opposed to crippled stats.
