The Ceremonial Urn is a craftable post-Moon Lord boss-summoning item that is used to summon Supreme Witch, Calamitas. It can only be used at an Altar of the Accursed.

When the Ceremonial Urn is used, a square arena comprised of Arena Blocks will be created around the player which can only be destroyed by the Crystyl Crusher's right-click. The player appears in the center of the arena, making it a high priority to use the item in a proper location.

The arena generated is 159x159 blocks (inner available area is 157x157 blocks) and 127x127 blocks (inner available area is 125x125 blocks) in Death Mode.
