A mysterious astrologer.
Esmeralda manipulates Stardust and Frostmoon: Stardust deals Physical Damage while Frostmoon deals Magic Damage and gives the target a shield equal to 135% of Frostmoon's damage dealt. Each Basic Attack deals (+100% Total Physical Attack) Physical Damage and 100 (+75% Total Magic Power) Magic Damage. The damage dealt by Esmeralda ignores all shield effects and gradually converts her shield into HP.
Esmeralda works well against heroes with shields, like Akai and Lolita, because her skills not only ignore their shields, but she also converts them into her own.
Esmeralda is countered by highly mobile Marksmen, such as Karrie and Lesley, because she lacks the burst damage to finish them off quickly and can't keep up with their mobility.
