Moving Around Other creatures
You can move through a nonhostile creature’s space [but] you can’t willingly end your move in its space.
Is that “end your move” at the end of your turn or if you stop to attack? I had a player who wanted to move into another friendly character’s space, attack a hostile, then sidestep behind a wall.
Grapple rules seem to be geared towards a constant struggle between two or more combatants. But are there any rules around, say, throwing a wounded NPC over your shoulder to bring them to safety, picking up your party member’s trio of pet rats, or having one of the creatures concede during a grapple? For example, what sort of action is it, and does doing so impose any sort of penalties?
