Gnawhole

Add 1 to chanting rolls for friendly SKAVEN PRIESTS within 3" of this terrain feature, and add 1 to casting, dispelling and unbinding rolls for friendly SKAVEN WIZARDS within 3" of this terrain feature.

You cannot move a model over this terrain feature unless it can fly, and you cannot more a model onto this terrain feature or set up a model on this terrain feature (even if it can fly).

After territories are determined, you can set up this faction terrain feature more than 3" from all objectives and other terrain features, more than 18" from all other Gnawholes in your army, and wholly within 8" of the battlefield edge. If both players can set up faction terrain features at the same time, they must roll off and the winner chooses who sets up their faction terrain features first.

Once per turn, at the end of your movement phase, you can pick 1 friendly SKAVEN unit wholly within 6" of this terrain feature and remove it from the battlefield. Set up that unit again wholly within 6" of a different Gnawhole in your army that does not have any enemy units within 3" of it, and more than 9" from all enemy units.
