Zehtuka's Pack

Zehtuka's Pack is a mysterious item that can be found in the Poisoned Outcrops,The Sulfurous Wastes, The Shattered Ravines, The Alkali Pan, The Ruptured Heart or Joko's Domain. It has a chance of appearing in any of those explorable areas, but each area has only one spot for it to appear at.

It behaves exactly like a bag that's been upgraded with a Rune of Holding. It can be equipped in the inventory! The pack cannot be dyed.

Most likely it belongs to The Great Zehtuka.
