Hello there to all! I just bought tha game and i have one question when a heroe equiped with two swords attacks does he roll all the dices on both cards ?

thank you

No. If you have two weapons equipped, you must choose one to use whenever you attack.

If both of the weapons are melee , you get to add the Off-Hand Bonus of the other one (if it's a sword, that's +1 damage). That is the only benefit you get from the other weapon. Otherwise, it is just as if you only had the one.

Once equipment destruction becomes a issue in the expansions, having a second weapon equipped is an insurance policy of sorts.
