If you use 2 swords in Savage Worlds, do you get a wild die for each attack in one round, or do you just get one for the main hand attack and none for the offhand? I know it would be the same kind of action (attacking) but it is with two different hands/weapons.
You get one Wild Die per action. Each separate weapon attack counts as a unique actions. Hence you roll a Wild Die for each hand but you still get the Multi-Action penalty. See Two Weapons in the Savage World Deluxe rule book.
You can only roll each skill once per turn, so you treat attacking with each hand as if you had a "rate of fire" of two. Roll two Skill Dice and one Wild Die. Take the two highest, and factor in any mishaps should a 1 come up on one of the Skill Dice. Don't forget to factor in the off-hand penalty if the character isn't Ambidextrous.
If someone decides to spend a Benny because of poor roles, it's 1 Benny per Skill Die.
