Yea, I also got 0 eidolons of any sort from the raid gacha last night. Looking at the wiki, the table still contains eidolons, so probably a bug. Wonder if the bug was through the entire event or during a particular time period?
Also, 907 tickets got me 3 of the SSR weapon and... 3 SRs. That's probably a record low of SRs from a raid gacha for me yet. This entire calendar year so far has been terrible for me in that regard.
And I don't even know what I'm gonna do with the 3 extra Tartarus arcane. No real room for a 2* after Medjed adds two more SSRs to thunder next month. Sure, Pride (S) on Medjed gun is less than optimal, but my thunder grid could use the defender aspect.
