Since we have been playing Descent, I have come to love ettins. Their throw ability is such a fun ability to shake things up and get heroes out of their defensive line. Their act I surge damage (+2 for minions, +3 for master) deals some sweet damage. But, as we are finishing up our first part of our first campaign, I am preparing for act II. I find myself stunned that for the act II ettins, their surge damage has been nerfed (+1 minions, +2 master).
Is this an error? Why would their damage ability drop?
