Monster Natural Attack Calculation


Rules Questions


When calculating a monsters attack for primary you use their BAB + Relevant Abi Score + Size and for secondary the same but 1/2 of the Abi score and -5. As for creature that have only on natural attack the use all the same as the primary but get 1 1/2 the Abi score. So 2 claws do not classify as 1 attack it would only have to be on claw correct.


Actually (assuming this was supposed to be a question and not a misposted response), if you are calculating the "to hit" bonus for a natural attack it would be as follows:
Primary: BAB + Str or Dex bonus (depending) + Size + Sundry "to hit" bonuses
Secondary: BAB + Str or Dex bonus (depending) + Size + Sundry "to hit" bonuses - 5
Single: BAB + Str or Dex (depending) + Size + Sundry "to hit" bonuses

You do not apply 1/2 ability bonus on "to hit" rolls. That is for damage only.

Calculating damage would be as follows:
Primary: Base damage + Str bonus + sundry magic bonuses
Secondary: Base damage + 0.5 Str bonus + sundry magic bonuses
Single: Base damage + 1.5 Str bonus + sundry magic bonuses

As to whether two claws count as one attack or two, they count as two. If your monster can only make a single attack, then it can make a single claw attack (at the Primary attack hit and damage calculations). If your monster can make a full attack, then it would get to use both claws (each at the Primary attack hit and damage calculations). This is because, while your monster can only use one attack, he still has multiple natural attacks and therefore does not qualify for the "has only a single natural attack" criterion for using 1.5 Str bonus.

I hope I answered your question.

To add to the above, I want to emphasize that natural attacks are either primary or secondary irrespective of how you use them. It is possible for a creature to have a single secondary natural attack (see: horse), which always receives a -5 to hit for being secondary. It is equally possible for a creature to have several attacks which are all primary and thus all have the full attack bonus (see: Hydra).
On top of that, some primary attacks always get 1.5x str bonus to damage, whether used by itself or as a full attack (Bite may be the only one, IIRC). Other than that, the above post is accurate.
Lastly, a creature with multiattack only gets a -2 on the secondary attacks, rather than -5.

The 1.5 bite rule is for dragons only. A non-dragon monster with a bite and two claws deals x1 str damage on each of its three primary attacks.

Thank all of you for your help. I am making an excel file for all the beastary monsters. I am just double checking the numbers on all of them before I input them in.

Any chance you could make that file public once you finish it?

Yes I might submit it on paizo main site and the pathfinder SDR
