The ground floor is reception and artefact accidents. Inside, in a reception area filled with rickety wooden chairs and outdated issues of Witch Weekly, visitors are greeted by the Welcome Witch, though her demeanour (at least on busy days) is less than welcoming. This reception area seems to double as a visitors' entrance and an emergency room waiting area, as it is often filled with wizards facing strange ailments, such as hands sprouting out of their chests or steam pouring from their mouths, and Healers clad in uniform lime green robes hurry busily through the room.

The receptionist helps anyone who is unsure where to go, incapable of normal speech, or unable to remember why they are at the Hospital.

Artifact Accidents deals with cauldron explosions, wands backfiring, broom crashes, and so forth.
