So, I ask a question: How can these abilities be combined into a cohesive martial arts style usable my Monks that are non-standard races? I would require any such character to take the Multiattack feat. That seems completely reasonable. But I am at a loss as to what to do next. A special feat to allow the use of natural attacks with a Monk’s class abilities? That seems to be too big of a penalty. Most races that have natural attacks already pay a level advancement cost.
That's EXACTLY what I have done -
house rules errata: Add the following lines to the Multiattack Feat:
Special: This feat allows creatures with natural attacks to use their natural attacks in a Monk's Flurry of Blows. The natural attacks count as the creatures base unarmed damage, and improve as the Monk gains levels. For iterative attacks beyond those granted by the creatures natural attack style, use the attack with the highest frequency or lowest damage potential, in that order, before adding remaining attacks.
In the case of a lizardfolk, the claw/claw/bite routine is 2 claws at +2 (1d4+1) and 1 bite at +0 (1d4) (natural). For the lizardfolk monk without Multiattack, the flurry of blows would follow the normal progression of two attacks at +0 (1d6) (lower total damage potential, and with worse chance to hit - why even BECOME a monk?). For the lizardfolk monk with Multiattack, the flurry of blows would progress as follows: damage at 1st level would be 2 claws at +0 (1d8+1) and 1 bite at -2 (1d8) (adding one attack and subtracting 2 from all rolls to hit, ending up with the normal claw/claw/bite routine but at a higher damage potential); damage at 8th level would thus be 2 claws at +7 (2d8+1) and 1 bite at +7 (2d8) followed by another claw at +2 (2d8+1). At 12th level, the lizardfolk monk would be a true terror in close combat, with 3 claws at +11 (3d6+1) and 1 bite at +11 (3d6) followed by a final claw attack at +6 (3d6+1). Finally, at 16th level, the full potential of the lizardfolk monk's flurry of blows is felt. The creature will have 3 claws at +14 (3d8+1), a bite at +14(3d8), another claw at +9 (3d8+1), and a last bite attack at +4 (3d8). That's a boatload of damage. And that's assuming the monk is putting all his level based stat bonuses somewhere other than Strength. Is that balanced over time for one extra feat? Compared to the human monk (who has an extra feat to play with, as he didn't need Multiattack) at +12/+12/+12/+7/+2 (2d8)?
With the level adjustment inherent in most creatures with natural attacks (in this case +2 EL), yes. I think so.
