NINJA GAIDEN 3

Story related… Cannot be missed. After you fight the boss battle of Day 1 the trophy will unlock after defeating this boss and viewing the cutscene.

Day 1 End Boss:
The strategy I use in the video and will change after the illusion version you fight in Day 4 is make sure he’s following you and then do an onlanding UT. Release the UT before he approaches you. If you release it as his attack connects you will take block damage or colliding damage. Rinse and repeat. Once you clash sword, smash . After winning the clash, he is vulnerable to a combo. The best thing to do is . The repeat the strategy again and before you know it he will be dead.

Video below is a good example of defeating this boss on Master Ninja Difficulty
