Disaster! This is an Attack to Destroy any Place. It does not require an action. Its Power is 30 against a Coastal Place, 24 against any other Place.
This is not an Instant attack; any group can use its action to aid the victim (but not the Kudzu).
If the attack succeeds, the target is Devastated. If the die roll succeeds by more than 6, the target Place is completely destroyed!
