The primary "ability" we've seen the druids use is knowledge.

We've never seen them in a fight. But they know how to defend themselves through other means.

We've seen Ms. Morrell defend herself. Her actions were purely defensive though, tossing a Mountain Ash circle.

Details on that are on the Alpha Pact page.

The same holds for Deaton - using the Mountain Ash in his clinic and outfitting the McCall's home with the same - in using his knowledge as a defense.
