Burning Strike is the move when you increase damage by hitting buttons at the right time. Every character has it on his or her Revelation Flow. Collect the blue orbs that enemies drop then hit R1 + Square in front of an enemy to execute. It just takes a bit of practice, and each character is different. I practiced with Jaster until I got it. Burning Strike Level 1 has only five buttons in the sequence. You must hit all five buttons correctly and receive a "Perfect" for the trophy to fire.
