How it works in Champions
Has a 20% chance to poison the target. This move becomes a physical attack that makes contact if the value of ((((2 × the user's level / 5 + 2) × 90 × X) / Y) / 50), where X is the user's Attack stat and Y is the target's Defense stat, is greater than the same value where X is the user's Special Attack stat and Y is the target's Special Defense stat. No stat modifiers other than stat stage changes are considered for this purpose. If the two values are equal, this move chooses a damage category at random.
“This move is either physical or special—whichever will inflict more damage. This may also poison the target.”
