One of our players is playing Trenloe as a berserker and in our last quest wanted to use Trenloe's heroic feat in conjunction with the whirlwind skill. I allowed it because the wording of the feat states that it must be used when performing an attack, not an attack action, which would be different. As per monster rules, any skill or ability that allows a figure to roll attack dice counts as an attack whereas an attack action is a basic melee or ranged attack that follows normal rules from the rulebook. Did we get this right?
Also, the feat states that it removes a defence die from the target while the whirlwind skill states that all adjacent monsters are targeted. We decided that each affected monster would have one defence die removed. Also correct?
