We know the current banner doesn't end till the 17th, at least.
In any case: the Jurota experiment went ok, in that the next 2 Special attempts were successes. But the first was so good that only one character died on any team (and mine was one of the full ones, I should say), and the second had us all almost fully wiped with the win at the very last second, so... hard to judge! He did survive much longer than Verica without babysitting... but I can't say if her healing would have helped more in some cases.
Still, maybe survivability while I can do more damage due to focusing on attacking is best, so I'll be using him more going forward (though not pushing his mana beyond the second circle I had already completed last week). Don't have any regrets about using Verica all this time, though, since most of my Special attempts were successes to begin with. And replacing him with her for most of this time was the only way I ended up with two good katanas such that I could do this at all. If anything, it's just nice to know my prior prep of him paid off long term, hah.
