The user blasts the target with virulent slime. The more it is used in succession, the more likely it is to poison or weaken the target.
Move Description
The user spits out a deluge of contaminated slime that makes the opponent feel sick and uneasy. Frequent buildup of this slime makes opponents more and more likely to succumb to its effects.
Effect
Has a 10% chance to poison the target and a separate 10% chance to lower the target's Special Defense by 1. Each effect chance doubles after every time this move hits consecutively, maxing out at 100% each. The effect chances reset if this move misses, the user leaves the field, or another move is used in between uses of this move.
