I tried this for my 3rd at attempt at honour. It ended in failure, but was pretty fun until that point. I went for Tempest Spore Druid, the idea being to get the wolf form for flavor and sneakiness while still preserving something of the Clerical trope. Maybe she should have stuck with the Wolf though, cause Ketheric and the Nercomites nailed her as an Owlbear. Spore Druid for her was pretty fun, you still get the shapechange there but then also a bunch of fun summons. I think the Grove gives every character an excuse to dip into Druid if we want them to, and the Underdark interlude could give anyone an excuse to dip into Spore Druid pretty readily.
