Hero/Monster attacking...

By IAMSpiderman22, in Descent: Journeys in the Dark FAQ Update Discussions

So I just found out last night that monsters are only permitted to use one of their actions to attack. I was looking in the rule book to see if heroes were only allowed to attack once as well and it is not clear.. movement says you can double move but attacking does not say. So do I assume they are only allowed to attack once as well?
