I am convinced that the item Blackened Crest ( http://wiki.spiralknights.com/Blackened_Crest ) is broken and will never reach the hands of a player until the developers check the code and fix it. Now you may be wondering how do I know the item is supposed to be obtainable currently? The recipe for Crest of Almire (http://wiki.spiralknights.com/Crest_of_Almire) is purchasable, and it requires the Blackened Crest. Leading to 3 different conclusions...
1. The item is obtainable, but no one has figured out how to obtain it.
2. The item is purposely unobtainable, and the Crest of Almire recipe currently serves as a crown sink.
3. The item is unobtainable by accident.
Personally I don't think option 2 is the case, it would be a really cruddy way to tease players like that. This leaves options 1 and 3. I'm going to try and figure out which one it is. I'm putting up 5000 crystal energy for the first person who shows me this item in a trade. You don't need to trade it, you just need to show it exists, and the CE is yours. I'm going to goad my friends and guildmates to add to this pool, most of them are convinced that the item is unobtainable.
FWIW this character has more then 7 days played, and it's collected 100+ Almirian Seals. There are others with more seals and playtime. Blackened Crest does not drop from Firestorm Citadel or Vanaduke. If a patch comes, I'll close this deal for a few weeks, because I'll assume this was finally fixed. Get to hunting!!! 5K+ CE and eternal glory is yours to find Blackened Crest before the next patch. This is not a joke, it's bothering me that no one has seen this item.
EDIT: Vishnalo was the only person to claim they had it, and I've been unable to confirm he does. The 5K CE will be his, or no one else's as I've revoked the offer due to no longer caring. Good luck finding this item. I still don't think it exists.
I am surprised that it hasn't been found yet either. I've done a lot of FSC and Vanaduke as well. I've heard that it drops from the guards in the 3rd stage of Vanaduke, but I think that's all just rumours. We even kept Vanaduke alive for a while in phase 3 and farmed the guards repeatedly for a good amount of time to try and see if one would drop. Oh well. I guess we'll just have to wait and see. Hope someone finds it :P
