Heroic Opportunities
"Fighting Chance" initiates a Heroic Opportunity for you and/or your group. When starting an HO make sure others in the group are aware that you are doing so so that they do not interupt the chain needed to complete it. Listed below are the HOs start by a Fighter / Crusader / Paladin since if someone else starts the HO they will want to control the outcome.
