Forodwaith Glacier
This  is a rare biome that appears as a plain made out of pure ice. The ground lies several blocks under the top layer.

Frost
When staying in Forodwaith, the player can get the frost effect, which blends the screen in white for a short time and deals one damage (a half heart) to the player. This effect comes in distances of ~20 seconds.

Warg fur armour protects against this effect.
