Fighters afflicted by the curse status condition are shown to be burning in purple flames with a hint of red flicker around them while they take damage, and use their grabbed facial expression.
Eiha and Eigaon's Curse damage is set, though the amount dealt in total differs between the variants. This is achieved through a rehit rate and a set timer.
