Nitroglycerin is a vial of chemicals used in The Dig Site quest which, when combined with ammonium nitrate, ground charcoal and an arcenia root, create a chemical compound. It may be obtained by using an empty vial on the barrel with a skull & crossbones symbol before being brought to the archaeological expert for identification. If the barrel has not previously been opened, a trowel may be used on it in order to do so.
When dropped, a vial of unidentified liquid does 25 damage to the player, this damage is increased to 35 if dropping a vial of nitroglycerin. However, neither can kill the player in the event that the player's Hitpoints are already 25 or below. They may be alchemised or destroyed using the incinerator to safely dispose of them.
- In real life nitroglycerin is the main component of dynamite and also heart medicine. It is too unstable to be handled in its pure form.
