Need some assistance with my hack, maps, events, graphics

On monsters physical damage instead of the random 56-63 could the range be widened to say 16 to 84?

It's entirely possible. It may present a case where the physical damage dealt by two of the same enemies would vary drastically, but if you're okay with that, implementing the new range should be quite easy.

As for defense, is it possible to do something similar to the physical damage to use Stamina and Defense?

Yep, that should be quite easy as well.

I hope you don't mind all my questions. Just trying to learn.

Not at all. I'm a helper. 0:-)
