|Examine||The root of an arcenia plant.|
Arcenia root is a quest item used in the quest The Dig Site to make Chemical compound along with nitroglycerin, ammonium nitrate and ground charcoal to blow up bricks blocking the path below digsite. It is obtained from tunnels where players can only enter with invitation letter. You need 10 agility to enter. It is also found at Senntisten Temple.
- After destroying the bricks under the Digsite, the Arcenia root spawns seem to shift to different locations - one of which is obscured completely by the sloping ground but can still be picked up. This hints that the dungeon after the explosion is actually a separate copy of the dungeon, which seems to be a common solution Jagex uses for changes made in quest areas.
- The graphics of the root resemble the old model of the Limpwurt root.
- During an unknown update in 2012, the root was recoloured to a grey-black colour.
- Currently, the Arcenia root's only spawn place is under the Dig Site, near Doug Deeping.
