The channel divinity option champion's challenge states that on a failed save, a creature can’t willingly move more than 30 feet away from you. How does this work with large creatures?
PHB states about ranges:
To determine the range on a grid between two things-whether creatures or objects-start counting squares from a square adjacent to one of them and stop counting in the space of the other one. Count by the shortest route.
A large creatures occupies a 2x2 area; where in this 2x2 area does the square determined by the range have to be? Can it be the nearest square, and therefore large creatures could actually move 1 square further with champion's challenge, or does it have to be the furthest?
