I can't get counter attack to work. I have set the Battle Settings -> Base Counter Chance to 100, and also set the Override Settings -> Base Counter Chance to 100 in Combatants settings. Also, I have checked the enemy's ability Ability Settings -> Counterable. The counter info in Battle System ->Battle Texts is also set. Battle System->Turn Based Battles->Options->Can Counter is checked too.
But still can't get it to work. What else I should try?
