# ║ A mod for Yanfly's Learn Skills script* Required         ║
# ║ Lets you specify what skills each actor can learn,       ║
# ║ and at which levels to learn them.                       ║
# ║                                                          ║
# ║ Use notetag on skills <learn require actor level: x, y>  ║
# ║ Sets the skill to require the actor x's current          ║
# ║ level to be y before the skill will show up in the       ║
# ║ actor's skill learning window.                           ║
# ║ x = actor ID, y = actor level                            ║
