The spell Tripvine will attack anything in a 10' area. It seems to have no limit to how many times it attacks, or how many creatures. So if a swarm crosses it, what happens?
And is it different if the swarm is a centipede swarm, bat swarm, or monkey swarm?
I would argue that the swarm counts as a single creature, so Tripvine doesn't target each component creature of the swarm.
In this way, I don't even think that Tripvine works against a swarm. They would be immune.
In any case, Swarms are immune to trips, so it doesn't matter.
Swarms are immune to trips

Thanks!
