How to beat Sin End Game (No grinding or power leveling!)

Boss fight 01:11 Final Blow 6:17 Cutscene 6:32 7:50 End Cutscene Update: 1. Cast Hastega 2. Do an armor break with auron or one of your other characters 3. Hit him with your strongest characters. You don’t need to have summons You don’t need to have overdrives ready. You don’t need a delay buster (In the video you see me use delay buster but Sin is immune to it so it was ineffective anyway) In the end I summon Valefor who had a full overdrive bar, and ended it with a 9,999 attack. I think I would’ve killed sin anyways even if I continued normal attacking with my people. But I could be wrong. This is also how to beat sin with a casual playthrough. No grinding or power leveling involved. You have to beat him within a certain amount of turns or he finishes you with his overdrive I was discouraged at first too, and thought I needed to grind more. I didn’t, just be confident and hit him as many times as possible. Good luck! Update: June 13 2025 I’ll probably be doing another playthrough of FFX10 soon, subscribe to stay updated.
