For the second time in a row we got to the last confrontation with Coalfang only to be defeated, one time for failing a Last Stand and the second one for being short of just one action to end the campaign before the threat get too high. In the first try we had Aragorn-Pathfinder and Gimli-Guardian, for the second one Elena-Musician and Legolas-Hunter.
In both cases we found our attack potential lacking, especially when fighting Coalfang for the second time where she is basically immune to all attacks modifiers, so you simply have to be able to deal huge amounts of damage as soon as possible.
Are there any tips you can give or would anybody simply be willing to share its experience?
