I did get summer Ch'en on daily rolls. Got all the drops from stages as well. I just need to finish Ex and So now.
Congrats!
The EX stages were pretty easy imo but DH-S-4 was a pain for me. Really needed precise skill timing and placement. Well at least I'm done now. Just the "mini" annihilation left. Hopefully not too hard. Then back to farming for ROCKS.
But before that, limited banner will be ending soon so on that last day, rolling everything for max pot Summer Ch'en. Admittedly whaled for this since I want to have some spare rolls left. I even bought the instant Elite 2 voucher for a 5 star. Will probably use it on Nearl for the luxury of having another healing defender.
