i would think setting it to the mode where the overdrive increases as you attack would be good but the problem is that it seems to be relative to the amount of damage a character deals which is a down fall for Yuna so which is a good mode i can set the overdrives to to get the most SP for all participating characters
i already have an area to grind but i want to try and get the most SP out of them
Best Answer
There isn't one definitive answer for which is the best Overdrive mode since it's dependent on the character and who you're fighting.
For grinding out regular enemies that you kill pretty quickly, Warrior or Slayer is probably your best choice since you'll be doing most of the damage.
For enemies that hit you with more powerful attacks, Stoic or Comrade might be your best option for your damaging characters whereas Healer could be used for Yuna.
I would avoid using Ally since it charges very slow. I would also avoid Coward, Hero, Daredevil, Tactician, Avenger, Sufferer, Victor, Victim, Solo, Dancer, or Rook since none of these are very well suited to grinding.
