Unfortunately, the references are quite dated (3+ years old). Also the second part is clearly marked with a caveat of "My Interpretation". Which means that was how I was managing the Fortress at the time. To be more specific, the "accident/mulligan" was always looked at to see if it was truly an accident, e.g. city guard in redhorn getting one shot, conjurer angel fight, etc. They were handled exactly as Padwei described. You have to look at every situation and judge accordingly.

Needless to say, how I handled fortress was how I alone handled it. There are new/old ways of looking at things now.
