As mine.
Actually, looking at the bottom ofthis Wowhead guide, it appears that all of the sha-touched weapons drop from either the last boss of Heart of Fear (Empress Shek’zeer), or the last three bosses of Terrace of Endless Spring (Tsulong, Lei Shi, or Sha of Fear).
Since we were talking about rogues earlier (Sarabellum1976’s toon), the roguish weapons (agility fist weapon, agility dagger) drop from Sek’zeer and from Lei Shi (third boss of ToES), respectively.
Still, they’re not actually necessary to continue on the cloak questline. You get the sha-touched legendary gem at the end of Chapter I, but you can only use it on a sha-touched weapon. Those weapons are completely outclassed now by the Siege of Orgrimmar drops. I went to the trouble of getting Taoren, but it’s just sitting in the bank with the Crystallized Dread legendary gem and the additional prismatic socket attached. Because I’m a collector. Go figure.
The only useful thing I’ve gotten out the cloak quest line, other than the cloak, is the legendary meta gem from Chapter III. That’s a good one; frankly, there’s nothing better to put into a helmet meta slot right now.
