After reading a few AP reports recently, I realized that the Healing text is poorly worded. So, I updated the FAQ with a clarification. Here it is:

Q. The book says, "You heal one wound box, plus one extra box per victory if you win." What does this mean?
A. This is poorly worded. Here's what happens: When you take a Healing interlude, first you automatically heal one wound box. Then, you heal an additional box for each victory on your roll. This means that even if you fail your healing roll, you still heal one wound box.
Sorry for the confusion.
