There is some speculation there might be another Kingdom Hearts event sometime in December due to the Kingdom Hearts 3 dlc releasing.
In addition to that, we should be getting wave 2 of the Anima Lens shop sometime around the end of the month, and if I recall, there should be a 15 mithril realm refresh coming up at some point soon.
I sadly only have his first glint and no AOSB. Also sadly, Heca is already one of the 2 5* magicites I've already managed to beat. Was more curious if the AASB would allow me to beat Adamantoise.
