Treasure Boxes are items in Horizon Zero Dawn that are obtained as quest rewards or through exchanging resources with merchants. The contents of a Treasure Box are dependent on the type and can include anything from Metal Shards to Resources, Modifications, Ammunition, Traps and Potions.
There are four special merchants in Meridian that trade special Treasure Boxes unavailable from general hunting goods merchants. As of the installation of The Frozen Wilds add-on, there are two additional special merchants found in the Cut that provide reward boxes in exchange for collectibles as well as new Banuk Mystery Boxes obtainable from Bluegleam merchants.
Most treasure boxes contain a random assortment of predetermined loot based on prescribed probabilities, with different possible drops appearing at a particular rate each time the box is opened. The contents of a box are pooled into groups based on the likelihood that an item will drop.
Guaranteed Loot: These items are guaranteed to drop when a box is opened.
Guaranteed Loot Chance: Upon opening the box, the player has a guaranteed chance at receiving the items in this group, though the rate at which they will appear and the quantity may vary.
Possible Loot Chance: Upon opening the box, the player has a possible chance at receiving the items in this group.
Not all boxes contain all loot groups. On the pages for individual Treasure Boxes, the number in front of the Guaranteed and Possible loot groups indicates how many of the items within the group the player will get. For example, when a box is opened the player is guaranteed to receive one item from within the group labeled "1X GUARANTEED LOOT" and two items if the group is labeled "2X GUARANTEED LOOT."
The Machine Scavenger Box is unique in that the contents of the box are dependent on which machine the box is looted from. These boxes will never contain a loot item that could not normally have been looted from that particular machine.
