I was thinking about crazy optimizations today and I’m surprised we don’t hear more people talk about this combo. A cleric that can cast lvl 3 spells can concentrate on spirit guardians and wild shape, and by becoming a large creature you can create a 40 ft field of fast moving justice taking the dodge action - that include spider forms, which allows ceiling walking to create the disco ball of death moving around a room out of melee reach.
I’m surprised I’ve never seen this build being abused.
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.
