After Tom mailed his one hours worth of loot, I decided to optimize his WOW gold farming hour. I took 12 of his Essence Of Air added 12 Large Brilliant Shards and 3 Vellum. I sent these 'matts' to the guild enchanter and had him create 3 Scroll of Weapon Enchant - Agility. Scroll of Weapon Enchant - Agility is going for 500-800 gold on my server. This upgrade to Tom's farming hour will yield a minimum of 1500 WoW Gold.
