An actor can learn skills based on the class learnings. Now, an actor can also forget any learned skills with the use of “Forget Condition Formulas”.
This new feature is available in the Learn Condition Formulas script, which provides various “learn conditions” for your class learnings, allowing you to create complex conditions for learning and forgetting skills.
You may need to get the latest version of the Core Learning script.
For example, you can have a skill that requires 50 atk to learn. Once you have 50 or more atk, the skill will automatically be learned. You can set the actor to forget the skill if atk drops below 50. Once the skill is forgotten, you have the opportunity to learn it again (unless it is a miss-able skill).
