Sharp enough for you? Trophy in Resonance: A Plague Tale Legacy

Hold to charge a critical strike, and let it land the killing blow on 25 enemies. The strike is slow, so use it on an enemy that is staggered (a yellow bar) or busy fighting Leni, Sophia's companion. Most players get this during the story. If you are short, Chapter V, Desolation It Wrought, sub-chapter Battle grounds, has plenty of enemies.
