Fuente (wowwiki): There are three types of rare specialty cloth that become available at Tailoring 415: Ebonweave, Moonshroud, and Spellweave. These are used to craft high-end items, such as epic robes and 22-slot bags. Tailors that specialize in one type of cloth will receive 2 pieces every time they use their cooldown; however, this is tied to the Burning Crusade decision to specialize in Shadowcloth, Mooncloth, or Spellcloth and is not a separate choice.

Soy sastre de fuego de hechizo (Spellfire), y hoy cuando usé mi CD de Spellweave, sólo me dio 1 cloth.
