Peira and Goblet of Oath Drop Rate Up

Hero : Peira
In this Drop Rate Up event, meet Peira, an Ice elemental Thief, capable of restricting and making enemies unable to be buffed while granting escort and increasing Attack of allies.
"The sole survivor of a tribe that was annihilated by an alliance of other tribes. Peira grew up with Arunka and considers her to be her sister, but she drinks from the Goblet of Oath to avenge her tribe and leaves the Prairie with her followers. Soon, she conquers the North that has long been segregated and builds the Khan Empire, a country of the Suin."
