A Druid of the Circle of the Moon gets a feature called Elemental Wild Shape which allows them to transform into elementals. I couldn't find anywhere that said one way or the other, do the usual restrictions of Wild Shape apply to Elemental Wild Shape? For example, can a Druid cast spells while shapeshifted into an elemental?
If not, the Beast Spells feature allows a Druid to cast spells while shapeshifted, but specifically mentions beast forms. Can a Druid with the Beast Spells feature cast spells while in elemental form?
