Polishing the Helm

Objectives
You are to enter Hibernal Cavern west of Dun Niffelem and collect 5 units of Viscous Oil from the Viscous Oils there.

You are then to return to Dun Niffelem and apply the oil to Hodir's Helm.
 * Viscous Oil (5)

Description
As you draw near the helm, you notice that the frigid environment is already taking its toll on the artifact's surface. What is now just a thin layer of ice will surely grow to envelop it entirely.

Not about to let your hard efforts go to waste, you resolve to scour the region in search of a solution.

Just as you set off, the eyes of the helm flash and an image of the nearby Hibernal Cavern enters your mind.

Progress
Frost is thickening on the helm as you watch, and icicles are beginning to form around its edges...

Completion
As you coat the helm with a thin layer of oil, the frost falls away and the surface gleams.
