Seething Flames of Hatred

To obtain this achievement, you must craft the epic weapon, [item=207011] ([item=203791] / [item=203792]). This returned with the re-implementation of previously removed Zul'Gurub items. Check out our guide for more information - New Secret: Craft Previously Unobtainable Zul'Gurub Drops. You'll have to unlock this to craft the Warblades.

Tips:

• The Zul'Gurub unlock is account wide. You can use multiple alts to farm out the pattern if needed.
• 
  
• Do not craft it outside the designated area as you will get [item=203989]. You will waste your materials.
• 
  
• You'll need 300 skill in Classic Blacksmithing.

How to craft the weapons:

1. Unlock the previously removed Zul'Gurub crafting system. Once you get Relics of a Fallen Empire you're good.
2. 
   
3. Obtain [item=203757]. This toy can be looted at the Cache of Madness portion of Zul'Gurub, just to the left of the pillar containing the Tablet of Madness.
4. 
   
5. Obtain Ancient Plans: Warblades of the Hakkari, Reborn. You can buy this pattern on the Auction House, or, farm it yourself. It drops off [item=203959] and may take you a long time to get.
6. 
   
7. Gather your crafting reagents, and one extra [item=19931], then head back to the Cache of Madness (where you got the toy). Ensure you are in the area the toy was obtained from. Use your toy on the ground, then use [item=19931].
