I am using the Celestial Fire Beetle as a summoned monster for a wizard. After applying the template I transfered the information to a form sheet for summoned/familiar creatures. I found that the CMB/CMD for the Fire Beetle in the Beastiary showed a CMB -1,CMD +9 (+17 vs trip). I belive this to be incorrect.
I calculated that the CMB/CMD should be:
CMB +1 = B.A.B. 0 + Str.mod. 0 + size bonus 1
CMD +11= 10 + B.A.B. 0 + Str.mod. 0 + Dex.mod. 0 + size bonus 1
Could anyone tell me where the -2 penalty is from, or confirm that I am correct ?
Thank you for your time,
Q
It's a -1 size penalty from being small for CMB/CMD, rather than a +1 bonus.
Brilliant ! could you please tell me where i can find this information as to show this to the rest of my Game Group ?
Thank you very much.
Q
It's in the Combat chapter under Combat Maneuvers.
CMB = Base attack bonus + Strength modifier + special size modifier
Creatures that are size Tiny or smaller use their Dexterity modifier in place of their Strength modifier to determine their CMB. The special size modifier for a creature's Combat Maneuver Bonus is as follows: Fine –8, Diminutive –4, Tiny –2, Small –1, Medium +0, Large +1, Huge +2, Gargantuan +4, Colossal +8. Some feats and abilities grant a bonus to your CMB when performing specific maneuvers.
OMG just found it in the core book page 199.
Thank you for helping me. <now I am off to read the book more carefully>
