Yirl not yet able to learn new abilities

[Tricky1975]

Working on it!

Let's put out the plan. Yirl will have to earn "business points" in order to learn new moves. He can earn business points by

• Scoring Aurinas
• Buying stuff at the store
• Selling stuff at the store

Also the current amount of Aurinas and credits can influence the points meaning you can technically lose points. My plan is to check the business points after every action Yirl performed and if he has the required amount of business points the new move will be put in the learn list, and then Yirl just has to perform a normal attack, like everybody else (except Crystal) in order to obtain the move.

I have not yet sorted out the exact formula, and the difficulty setting may influence the business score (making Yirl somewhat unique is he's then the only character in which this setting actually influences the easiness of learning moves).
