Moon druid is a very strong 2-level dip. It plays nice with Rangers, Fighters, Barbarians, Monks, and Clerics. All because most class abilities can be used while wildshaped, and because the Moon Druid’s buff to Wildshape punches so far above its weight for a level 2 feature.
I once played a 4-Elements Monk X/Moon Druid 2 build and being able to pull an enemy toward you with waterbending and then flurry of blows them as a Direwolf is awesome.
