Hello and many thanks!
When you roll d6 for an enemy/monster HP and get a 6, and in the case where that same enemy gets an HP bonus, instead of increasing their HP they attack twice per turn - roll d6 for each of these attacks.
This next point has shown me that I didn't put this instruction in the text - whoops! My intent is for the following to happen:
Some encounters require a COIN TOSS to determine which set of actions to take - HEADS representing an advantage to your character, presenting the option to incorporate an enemy into your party, let them leave and avoid combat, or to go ahead with an attack. TAILS will require you to roll on the accompanying table. This will definitely be an edit for the next version.
Thanks, please let me know if you have more questions!
Matt
