Deep in the icy wastelands of Valoran's easternmost pole, there is rumored to be a frozen loom. Its pedals, levers, and weave all made from smooth, pure ice. It is this mysterious loom that is said to be the origin of the magnificent Glacial Shroud.
Glacial Shroud is a fairly cost effective item: for the combine cost of 250 gold, it grants 10% cooldown reduction, 5 armor and 50 mana.
As one of the few items that grants a combination of armor, mana and cooldown reduction, Glacial Shroud is an affordable advanced item in most fighter or tanky mage builds, later to be upgraded for even more armor and other stats.
