Nidorina does 10 damage to itself, and don't apply Weakness and Resistance to this damage.
If Nidorina has any damage counters on it, this attack does 40 damage plus 20 more damage and the Defending Pokémon is now Poisoned.
When it senses danger, it raises all the barbs on its body. These barbs grow slower than NIDORINO's.
