Agree with the other comments, good addition to the core game, very classic Druid in the non-gaming sense. Would recommend adding Druidic language to the core class as part of Druidic devotion and a new Tier 3 spell that emulates a bit of the Wildshape capability that has become known for Druids in the gaming sense. Like a slimmed down polymorph with a prescribed list of natural creatures to choose from (Wolf, Hawk, etc), and possibly additional forms depending on alignment (Chaotic - Giant Spider, etc) but contain it within a spell casting mechanic as opposed to the main class. Then a player can choose to lean into that part of their Druid character or not.
