In UO, pretty much everything comes down to whether you're in range, out of range, interrupted/fizzled, or parried/evaded/missed. What I'm wondering is how hard, in a tile based game like UO, would it be to implement missile collision, so that there could be a straight line damage spell or the like that could manually be avoided just by movement? Or would it have to be a progression spell, like some of the specials that arc out with damage? Either way, be neat to have some things like in the game.
