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 and used to store items. The Bag will take up one of the spaces for bags in your inventory, so basically, the size of the inventory still cannot exceed 45 items.

Most likely it belongs to The Great Zehtuka.
