By default, a magic skill gives you the choice to target a monster. And a simple way to make a multi-hit spell would be is to either make it a random hit field damage or keep attacking a single monster until it is destroyed. But what I have yet to discover a way of accomplishing would be a spell that allows you to target a monster, and then use variables (or something) to make a spell hit said monster more than once without having to re-cast the spell. Does anyone know how something like this can be done? Also, this is being worked on in Rm2k3.
