R> command when killing monsters

[Ricauter 1]

 I want to know if it's possible to script that when you kill X mob in Y map, it exexutes Z command, like for example to add +1 to a counter, and when that counter reaches a certain number, then it executes a certain command, or when killing a monster it buffs you, I'd greatly appreciate on some help on how to create a script of this kind
