Hi,
These I could not find answered in the rulebook:
1) What is the effect of disengaging the enemy? Free attack?
2) When should you make attack opposed check? Opposed checks are generally always harder than unopposed. I would say that if you have two individuals fighting they are "opposing" to each others' attacks but this would not work as a standard game rule judging by the examples.
Would Active Defense make all incoming attacks "opposed"?
A bit lost..
