Nitroglycerin

Nitroglycerin is a members-only quest item. It is used in Digsite Quest to make Chemical compound along with ammonium nitrate, ground charcoal and arcenia root to blow up bricks blocking the path below digsite. It is obtained by using a vial to barrel with skull mark near the panning point, and is brought to archeology expert to learn that it's nitroglycerin.

Before archeology expert identifies it, nitroglycerin is known as unidentified liquid.

'''Beware! You take 35 damage if you drop the vial!''' You can get rid of it by alching it or placing it on a table. Many players using Dharok set use this effect to lower their hitpoints to hit higher.
 * When a player drops this they say Ow! The Nitroglycerin exploded! and they take 35 damage.
