What is the helmet rule for those of us who never played 1e?
Hmm? Granted, I'm going strictly from memory, here, (my book is at home), but I thought it was:The helmet rule stated that any suit of armor is assumed to come with a helmet which provides AC equal to the armor type. 10% of attacks will be aimed at a helmeted head. If a helm is not worn, then intelligent opponents will target the head 50% of the time.
