Formula: Enchant Cloak - Subtlety was dropped by Emperor Vek'lor in the Temple of Ahn'Qiraj in Silithus. This instance is generally not run anymore since the release of TBC, and as a result, the enchant became much harder to find.

However, in Patch 2.2 this formula became available from the Thrallmar and Honor Hold Quartermasters, using level 70 reagents. It requires reputation.
