Enables a Steel-type target to be hit by Poison-type attacks. It also melts away defenses.
The user spits a harsh acid all over its foe that easily warps and pits metallic armor, making it easier for poisons to seep through the resulting cracks. The acid is also potent enough to eat away at modified defenses, returning the target to its original, exposed state.
Resets the target's Defense and Special Defense to normal and prevents any further boosting until the target leaves the field. A Steel-type under this effect takes normal damage from Poison moves (but still cannot be poisoned). This move itself ignores accuracy and evasion modifiers.
