That was the closest battle of my Tidus only challenge yet! It was with Sinspawn Gui, I ran out of Antidotes so in a last ditch effort I used Spiral Cut even though I had 450 Hp left and had the poisin status on me. It killed him and poisin did 409 damage I survived by 41 Hp! Too close for comfort!

Well... I'll update here on the rest of my challenge....
