A cauldron is a magical, multi-purpose vessel crafted from a variety of enchanted metals, such as pewter, iron, or silver.
These cauldrons are central to a wizard's practice, serving not only as a container for brewing potions but also as a conduit for channelling and focusing magical energies.
Cauldrons were once associated with witches, but times have changed and a cauldron is a perfectly respectable item for a wizard to own.
