Difficult Terrain

[Qoff]

It is possible to set some areas in my map as difficult terrain? If not with the vanilla FG there is any plugin that allows that?

[Zacchaeus]

If you use the layers extension you could use tokens on another layer to represent the difficult terrain. Otherwise it's either theatre of the mind or draw squares or circles using the square or circle tool to show the areas.

FG has no way of calculating difficult terrain when measuring movement.

[LordEntrails]

The way I think of it is that FG only measures distance, it doesn't measure movement. i.e. it might be 40 ft from once place to the next, but it could take 60 ft of movement in order to cover that distance.
