How is the portion of the frightened condition meant to be interpreted:
The creature can’t willingly move closer to the source of its fear.
More specifically, what is meant by "move closer"?
Here are a few options I've come up with which may include some insights into the answer:
- The shortest linear path (ignoring obstacles) cannot be decreased
- This would mean I could not approach a wall when the source of fear (let's say a creature) is on the other side even if it increases the distance it would have to travel to get to me (say around a winding corridor)
- The distance that would need to be travelled to reach the source cannot be decreased
- This has the opposite effect of option 1. I could move closer to the wall, but not into the winding corridor that the creature is approaching from.
- The travel time to reach the source of fear cannot be decreased.
- This is relevant for cases such as difficult terrain, variable movement speeds, planar travel (would portals factor in?), and other such factors.
I'm sure there are other interpretations that I haven't come up that may be more in line with the rules.
