Hey, new kid here.
I did summon. I was set on getting all four from the start, but I really just wanted Chrom the most. Instead I pulles two Xanders, two Lucinas, five Camillas until I got Chrom and I stopped there because, my orbs...
(In the process I also got Azura, whom I didn't have, 5* Fae, 5* Sheena, and a duplicate 5* Cordelia).
It was totally worth it.
