I have a new player in my group who wants to play a besalisk (the four-armed cook that Obi Wan chats with in Attack of the Clones). He likes the idea of four-weapon combat.
I know that with two-weapon combat, you combine the two pertinent skills using the lower skill rank of the two and the lower characteristic rank of the two. Then you add an additional difficulty die to the pool. After the roll, you can spend two Advantages to hit with the second weapon.
How would I run four-weapon combat? Add another difficulty die? Upgrade difficulty dice instead?
My thought is to add the single difficulty die for multiple weapons as above, then upgrading for each additional weapon past the second. Is this reasonable, or should I simply add even more difficulty dice?
