Lesser Rune of Shielding - created through Blacksmithing (340)
Requires Level 55 Use: Applies the Lesser Rune of Shielding to your shield. This rune absorbs up to 1000 points of damage before it fails. Lasts for 1 hour.
The recipe for this item can be found at Mari Stonehand in the Wildhammer Stronghold in Shadowmoon Valley for the Alliance, and Rohok in Thrallmar in Hellfire Peninsula for the Horde. (Limited supply x1)
Even though the recipe is "yellow" when you learn it, it is good to use to get to 350 Blacksmithing due to its low material requirement
