Ramaladni's Icy Grasp

Korfax at Light's Hope Chapel in the Eastern Plaguelands wants you to bring him 1 Frozen Rune, 1 Blue Sapphire and 1 Arcanite Bar.

Fixing this band may prove to be quite challenging, <name>. You see, it was made from the very runes that form inside Scourge structures - like Naxxramas. Additional materials are also required but your main concern should be getting those frozen runes. Bring me what I need and I will restore the ring to its former glory.
