Thanks guys, i just defeated Dark Valefor. Granted, i started another game, got Anima and Magus Sisters straight away instead of unknowingly leaving the Besaid Destruction Sphere behind and ended up spending another 80 hours on the game . It wasnt exactly the most encouraging way to beat him either. I had done 300 000 damage, yes 300 000 damage, leaving 500 000 more damage left. I summoned Yojimbo and he used Zanmato and killed him off. I really wanted to kill him/it/her/whatever truthfully. Truthfully, i mean properly.
