Update, I have built something with this in mind. I want to make this simpler.
You need 1000 damage done for 100 hp, or level 2
1250 for 125 hp, or level three.
1500 - 150
1750 - 175
You get the point. Now it would be nice if it could have:
125 hp = 1.25 bow/sword damage,
150 hp = 1.5 bow/sword damage,
175 hp = 1.75 bow/sword damage.
I am basing the classes on whether or not you have a bow or a sword. There will be no other weapons, exept I plan to make the Rangers branch of into Marksman and something else, and Warrior into rogue and Knight. That is my job, using events.
Each quest uses variables, and checks which one you have.
