Nana's successfully transitioned into a deadly little mage and beyond, straight into 'overpowered' territory, so we're cutting down on some of her power, especially her Passive, to make her more vulnerable on the battlefield.
Passive - Molina's Gift
Cooldown: 120s → 150s
Skill 1 - Magic Boomerang
No longer slows enemies hit.
Ultimate - Molina Blitz
Slightly increased the interval between two attacks.
