For those, who need this trophy in a very fast manner like me (12 days of Christmas challenge cause of its ratio), you can do this in the very first level. Play on casual difficulty, go ahead til you get your first shield. Equip it using the option button and from then on parry with LT short before the enemies incoming attack. Don’t use your sword anymore, keep parrying with the exception of enemies using bows. This way I managed to get this as my first trophy in the game, should take you 20-30 min!
