Pinkymod/Sunswept Egg

The Sunswept Egg is a consumable Summoning item that can be rarely dropped by any enemy in the Desert or bought from the Merchant for 35 gold after Skeletron is defeated. If used in the Desert town of Eitd, the Sunlight Trader boss will spawn. It cannot be used if you are not in the Desert town of Eitd. It can only be used by the birds nest found just to the left of the pre-built arena.
