thul rune

A Thul rune is a low tier rune that can be socketed into armor and weapons in Diablo 2: Lord of Destruction and Diablo 2 Resurrected. A Thul rune provides Cold Resist +35% when inserted in shields or off-hands, Cold Resist +30% in body armor and headgear, and Adds 3-14 Cold Damage in weapons.

You can cube 3 Ort runes together to get a Thul rune. You can also obtain a Thul rune from nightmare countess. You can get a Thul rune from the normal hellforge quest.

A Thul rune requires level 23 to use. When you socket an item with a Thul rune, you increase the level requirement to level 23, unless it was already higher.
