If the Darach managed to catch Deaton, unless he has an agent who performed the deal, he couldn't enter in the Doctor's clinic if he was any kind of supernatural. As we know, the site if half build with mountain ash, who allows Deaton to block supernatural interference.

So, the Darach should not be a supernatural creature.
