The Shadow
Hero
Here's another approach:
Hm, this does look a lot more robust than the previous one.
I'm curious why you have the possibility of a die doing no damage at all? It seems like kind of a downer. You could just as easily say, "Each die with 3 or more gives you a Flurry Point."
Is it just so he doesn't outshine the fighter?
The downside is that you don't get the coolness of exploding dice. Sigh... Also, to make the math work here I've not added any str/dex modifier to damage with flurry. I'm thinking maybe the modifier should be added to Ki Strike damage... that way, a "mystic" monk could add Wis, a "hard-style" monk could add Str, etc.
Adding it to Ki Strike sounds appropriate.
