I have run into a weird situation, and all of my google-fu and PHB indexing has not been able to help me.
One of my players is running a monk and has on several occasions attempted to use grappling or pulling to get allies out of danger. I approve of the creativity but I'm not sure how it comes out rules wise.
There have been a couple scenarios that have come up so far.
1. A mudlord had an ally grappled and covered in mud while the ally was unconscious. The monk wanted to know if he grappled the mudlord and moved the mudlord away from the monk's grappled ally, would the mudlord lose his grapple on the his target. I ruled yes at the time (I figured the mud holding him would get pulled away) as I wasn't able to quickly find an answer with the resources on hand.
2. A large water elemental rose up behind the party and thanks to greater cleave it began to beat the crap out of the squishies. The sorcerer was looking particularly bad, and because of the reach of the elemental was unable to easily get out of range without provoking AoO. The monk, who has pretty good defenses, wanted to know if he could grapple the sorcerer and force his movement away from the large water elemental, taking the AoO on himself. This one I was a lot shakier on, and said that while grapple and pull actions exist, and forced movement doesn't provoke, I'm not sure about targeting an ally with either of those actions. It was a moot point because the creature had already taken an AoO that round, but as the monk is being played as being a selfless combat maneuver guy I suspect it will come up again.
So my questions are:
1. Can a grappler lose their grapple if they themselves get grappled and pulled from the target?
2. Can an ally be the target of a grapple or pull combat manuever, and if so, would only the person forcing the movement be a valid target of an AoO?
3. If an ally is a valid target of maneuvers like grapple or pull, can the voluntarily not resist? So the grapple/pull automatically succeeds?
4. Side question, I have not been able to find a good definition for "foe" or "opponent" or "enemy" as far as Pathfinder is concerned. Is it entirely subjective?
5. What actions can be done to move an unconscious hero in battle? Say, if they are actively drowning in water and mud, or taking area damage?
Thanks in advance for any help. I've been DMing Pathfinder weekly for 3 or more months now and once a month for almost a year and I still feel like there's a lot to learn.
