In 5e D&D, the coven of hags gets shared spellcasting. This enables them to cast spells with a shared amount of spell slots.
My question is, when they are not in the coven, aside from their own innate spellcasting, do they get their own spell slots? I am using roll20 to source this information, and it details a spellbook at the bottom of the page, with all the spells a hag can cast - including the innate spellcasting and the coven spellcasting. This is the source of my confusion.
