As long as Scizor ex's remaining HP is 60 or less, Scizor ex does 40 more damage to the Defending Pokémon (before applying Weakness and Resistance).

During your opponent's next turn, any damage done to Scizor ex by attacks is reduced by 20 (after applying Weakness and Resistance).

If the Defending Pokémon is an Evolved Pokémon, this attack does 50 damage plus 30 more damage.
