The diviner's headwear add-on is an item obtainable from Treasure Hunter or as a possible reward from an experience-earning Guthixian Cache. It can be used on a diviner's headwear to create a Modified diviner's headwear. Once the add-on has been added to the diviner's headwear, it cannot be undone.
When combined, it allows the player to claim a chronicle fragment and teleport 3 times a day to a chronicle hand-in location. These abilities reset daily and 3 chronicle fragments are received when 4 or more pieces of the outfit are owned. Additionally, while wearing the headwear, you have a 5% chance to save half the divination energy cost during weaving or transmuting.
