Ability Points (AP) are earned by defeating enemies and completing quests. You can spend them in the 'Abilities' menu to unlock new Eikon skills and upgrade existing ones. Prioritize upgrading your most frequently used abilities first. Fully upgrading an ability often reduces its cooldown or increases its potency significantly. Don't be afraid to use the 'Reset Abilities' option (for a small gil cost) to reallocate your AP if you want to try a different build. This flexibility allows for constant experimentation and adaptation to different combat scenarios.
