Shamans and Enchanters: Now in handy scroll form!
Moonglow Ink allows you make some really cool stuff. For example, at 35 skill, you can start making Scrolls of Recall, which act like the Shaman spell Astral Recall, allowing you to teleport home every 15 minutes, and all for the price of a vial of Moonglow Ink and a piece of Light Parchment. The scrolls go gray at 75, so you can churn out a lot of them as well.
At 50 skill, you can start becoming an enchanter’s best friend. You can make Bleached Parchment, which can be targeted with armor enchantments. Anyone can then use the resulting scroll to enchant their armor. So far, there’s no apparent level limit on these scrolls, so if that remains unchanged, they’ll be good even for the new Wrath enchantments. All of this and all it requires is one Moonglow Ink and some Light Parchment for each scroll.
Another 50 skill recipe is a bit of an enigma. The Mysterious Tarot, which uses 2 vials of Moonglow Ink, will produce a random card from the Rogues Deck. When you combine the Ace, 2, 3, 4, and 5 of Rogues, you’ll get a deck you can turn in to the Darkmoon Faire for a magic chestpiece with a random enchantment. The quest text implies that there will even be gypsies in various inns out in the world so you can do the the turn-ins any time of the month, although those gypsies don’t seem to exist yet. It’s worth noting that the Rogue cards may also be world drops — at the least, I have personally seen one drop off a Citizen of New Avalon in the Death Knight starting area.
At 100 skill, you learn to make Midnight Ink, which requires Dusky Pomace and goes green at 115. With this ink and 5 pieces of Light Parchment, you can make Treated Vellum, which can be targeted with weapon enchantments, then used by anyone to enchant a weapon. It goes yellow at 112.
