The following areas should probably be tagged as "natural" in terms of ranger/druid abilities, but are not:

Underdark - Beyond the Canyon

(Feel free to add any that you find.)

Many of the quest areas disable the natural area, resting is still restricted in QA which it should be but everything else should still work. Exampe: Gnomes.

Underdark - Freezing Cavern Underdark - Frozen Caverns Underdark - Frozen Wastelands And others in that vein, perhaps, should be considered "natural", providing that the extreme cold is actually natural.

It's not a bug in the super cold areas, for now anyways.

The Canal Ward still allows druids and rangers to rest in it.

We want our mushrooms! :(
