Immunity to fire damage. +100% fire effectiveness.
The character's attacks and spells duplicate the damage with the water element. +100% water effectiveness. 100% water resistance.
The fire damage is 100 + 20 * 9 = 280, and it is doubled. Then, the water damage is duplicated and doubled. In the end, the "square" receives 560 + 1120 = 1680 damage. At the same time, Erika herself does not receive anything, even if she is in the area of effect. Did I understand the principle of these passives correctly?
