So here's the combat system.

* For Dynasty Warriors-style battles, dice rolls determine how many enemies you kill in one turn. Your character charges in with the sword raised, I roll and spit out a number, and then you get to describe how you got there.

Ex:
P1: Hero charges into a group of goblins with his sword raised high and courage in his heart.
GM: [rolls a 3] 3 goblins charge at you. They look woefully unprepared to fight you.
P1: Hero guts the first goblin. Two other goblins charge at him. Hero lifts up the dead goblin's body and hurls it at them, knocking them down. He follows it up with a clean swipe that beheads them both.

EDIT: The PvP combat system needs more work.
