Just to clear things up, for anyone that didn't get it from the earlier post, you have to turn in the 10 encrypted twighlight texts to hermit ortell, and after a while he'll send mail to you. If you turn in the texts to the tauren in cenarion hold you'll get 100 rep bonus with the cenarion circle. To turn in the texts to ortell you have to do a different quest chain first, where you have to first locate ortell, then get the tablets for him. However, unless you're going for one of the recipes he sends to you, I'd recommend getting the 100 rep. It's better if you're going to be dealing with the cc a lot.
Ok.... Did the quest series and can turn them in to the Hermit guy... Yay! Turned in 20 yesterday, got 2 different packages in the mail - so yes you can turn in text several times.
But... All I got in one was a agility scroll and in the other and a scroll to create a crest of beckoming (whatever that is). No Breastplate plans ***cry***.
Sooo... not freindly with the guys yet - will presents become better when friendly?
This is the most common recipe... If i was you, I wouldn't buy this for more than 10g in AH... How do i know it's the most common one? Well, I've turned in 300 of those Twilight Texts(30 bags) and i've received this four times and the Runed Stygian Belt recipe four times as well.. I received the Runed Stygian Leggings only once... That one seems to be rarest along with the Darkrune Helm recipe.. Good Luck.. Going back to Silithus now.. I want that helmet :/
Oddly, these cam in the mail from Othell in Silithus. When you find the 3 lexicons for him, he offers a quest to turn in 10 encrypted text. I did that and got nothing but a bit of gold and XP (which didn't really help at lvl 60). A few hours later, I got a letter from him with this plan.
ok i have turned in the quest to the hermit 5 times already and i all i have gotten was the cloth version of this item for the first time all the other times i have gotten some stupid beakon thing.  Has anyone else been able to get  more then one recipe? I hope so cause if not its gonna be a pain to get all 3 recipies.
