Rejoice! For all those egg drops you get when you’re not playing summoner will actually have a purpose. From the 24th of August you’ll be able to exchange 10 x 10* or 11* eggs in for 1 Lambda Grinder. Fancy!
I mean the fact that 11* eggs are subject to the same exchange rate as 10* despite being rarer is a little strange, but they’ve done this kind of thing before with 10 and 11* weapons and units. The two are effectively considered the same category, despite one still being visibly less common than the other.
The upside is you can gain something from picking up all those SPECIAL EGG?s laying around at the end of emergency quests with the minor downside that you’re going to have to pay to untek them for the pleasure. It’s gonna be up to you whether you think Lambda Grinders are still worth picking up this way or not.
