Clarification on Animal Companions and Trip

[EvilKingCaliban]

So, after looking through the archives here, there have been several threads that came very close to answering my question, by none that seemed to hit it spot on the nose.

My question is thus:

If I have an animal companion with the Trip feature, say a wolf. He gets a free trip attempt as part of his attack action if he hits with the attack. If he has any situational bonuses to hit on that attack action, do they also apply to his CMB on the trip attempt?

I believe so.

From the PFSRD:
"When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus. Add any bonuses you currently have on attack rolls due to spells, feats, and other effects. These bonuses must be applicable to the weapon or attack used to perform the maneuver. The DC of this maneuver is your target's Combat Maneuver Defense. Combat maneuvers are attack rolls, so you must roll for concealment and take any other penalties that would normally apply to an attack roll."

So when you make the Trip attempt you would still use any modifiers effecting the attack associated with it (like the +2 if you were flanking).

Answer: most of them.

Things like flanking or Inspire Courage apply to all attack rolls, including combat maneuvers.

Things like Magic Fang will apply because trip, sunder, and disarm benefit from bonuses on the weapon that you are making them with.

But say, for example, you wolf was under the effect of an Invisibility spell. The bite would get a +2 for invisibility and be vs. flat-footed, but that attack would break its invisibility, so the trip would relatively be at a -2 and be against regular CMD.

Did that answer the question?

It did, thank you!
