Chaldea U-Summer Island

Self proclaimed lol

The latest MC is perfect for this as it works for Summer Miyu as well (who recharges 20% per wave too)

EDIT: ah, nvm, slight miscalculation, Miyu can't do it because I forgot I OCed Parvati beyond what I thought I did, but you can use one Tiamat's NP with the 10+10% MC as both are 80% at W3

I wanted saito because of his new rank up quest got tezca bro first in 3rd multi

Welp in 6th multi got saito sama :( not rolling for summer mama tiamat till grand archer release.
