Description
The Monks of the Way of the Open Hand are the ultimate masters of martial arts.
Comments welcome. I'm particularly eager to know whether you think the CR is correct.
Thanks.
Edit: I've added tool tips and the missing word in the Unarmed Strike bonus action in v2. Any other editing notes welcome.
I think it's a pretty good NPC Monk and basically what I was looking for. Thank you.
