Magic Demage Scaling

[Kasparas]

Now i was searching and searching for tutorials how to make magic demage scale after your will stat , so when i make spell "vital" to 50 , if my will is huge it'll hit even 300 , something like that , and so if you have great agility , you can protect yourself from magic , so strongest spells would hit less on stronger players . i know nothing about vb6 and stuff like that and am fresh to programming, so please can you write me a tutorial or a code to make magic demage scaling happen depending on will stat ? please
