The limited banner feature: Ho’olheyak - Caster [ST / Core Caster] , Melanite - Sniper [Close Range / Heavyshooter] and limited operator of this banner Muelsyse - Vanguard [Summoner / Tactician] .
As it is Limited banner you will get coupon for 10 pulls and 1 pull a day until the end of the banner.
