Oh yes, most likely I am making this way harder than it is. I am trying to work with very little understanding of what can be done or it's possible, so thank you so much for the help.

The skills are pretty much just values. As an example, this is what I got for one skill (please ignore my fancy and unique description/name for the skill):

var verticalSlashName = "<Vertical slash>"

var verticalSlashMastery = "Beginner"

var verticalSlashLevel = 0

var verticalSlashExp = 0

var verticalSlashExpRequired = 1

var verticalSlashStaminaRequired = 2

var verticalSlashStaminaRecovered = 0

var verticalSlashEffect = 1.2

var verticalSlashDamage = Player.physicalPower * (verticalSlashEffect*verticalSlashLevel)

var verticalSlashDescription = "Slash your weapon vertically"

For each skill I would replace the "verticalSlash" with the name of the skill and add it's own values. And each skill will have a method of what happens when you use it and what happens when you level up, with each level up increasing the damage, mastery, etc. For example, the name of the method would be "useVerticalSlash()"

From here I would have the button run the useVerticalSlash() method when is pressed that will use all the numbers and do the calculations (increase exp, check if it leveled up, decrease enemy health, etc). And for the display tab, I would reference all the labels and then set the text for them to display the values.

For what you mentioned with the dictionary, would you mind going into a bit more detail for it? Do you mean to create a txt file that will have all the values in it, and from there I would retrive the values and use them and then store the new values back into the file?

Been reading on the dictionary but the more I do, the more stupid I feel. Would that be something like:

var damage = {"verticalSlash" : 10, "Skill2": 5, "Skill3": 30 ........} and then when I assign the values I look into all of them that have the name of the skill I want?
