Combat is really simple, however we'll provide an explanation. In a combat situation one character launches an attack. The second party then chooses how to respond by, blocking, dodging, or canceling out. Once that's done the second party has the option to counter attack and lunch an assault of their own. This cycle continues until the fight comes to a conclusion. Now obviously it's more complicated than that, however that's the art of combat in a nutshell.
