I just thought of a candy that can raise PC ability score permanently.

Ability Score Candies.

Strength Candy: Can raise your strength score by +1.

Dexterity Candy: Can raise your dexterity score by +1.

Constitution Candy: Can raise your constitution score by +1.

Intelligence Candy: Can raise your Intelligence score by +1.
