Ammonium nitrate is a members-only quest item. It is used in The Dig Site quest along with nitroglycerine, ground charcoal, and arcenia root to make a chemical compound. It is obtained by using the chest key to open the chest inside the Digsite Dungeon. The key is consumed upon opening the chest. If you search the chest while your inventory is full, the ammonium nitrate drops to the floor.
After the player blow up the obstacle with the chemical compound during the quest, the chest disappears, preventing them from obtaining more ammonium nitrate.

- patch 20 May 2019 (Update):.
- Ammonium nitrate and nitroglycerine are now identified on pickup, and do not have to be taken to archaeological expert Terry Balando (though he is still able to identify any unidentified items you might still have lying around).
- Ammonium nitrate is used in some explosives with nitroglycerine. These are often referred to as ammonium dynamites.
