My interpretation of the rules is that the grappler can move freely as long as the grappled stays on the grappler reach. But I want to be sure.
What happens in the situation where reach is greater than attack range?
- A is an Otyugh and B is a humanoid. Keep in mind that the Otyugh's
tentacle reach is 10 ft. and the bite attack range is 5 ft.
- A is grappling B. B is 10 ft. away from A. A moves closer to B to make a bite attack.
- A is grappling B. They're adjacent to each other. A moves 5 ft. away from B to put himself out of B reach.
- A is grappling B. Both are at the edge of a chasm. A circles around B to be able to shove B into the chasm.
