This Seeking Tech guide will explain how you can beat Raleigh without taking any damage in Sly Cooper and the Thievius Raccoonus (2024) on PS4 and PS5.
Use the fooling video walkthrough as a reference:
For the first phase, stay on the same platform while keeping away from his shadow to avoid getting hit. You need to stay close to him so that you can attack him when he shrinks.
Use the same strategy as before for the second phase of the fight.
For the third phase, the platform will sink after he bounces on it twice, so you need to jump over to the next platform before it’s too late. You should also make sure that you stay relatively close to him for a quick counterattack.
For the fourth phase, he will swing his long tongue at you. Make sure to jump as the tongue begins to turn towards you. You can then finish him off when he shrinks.
