The Rogue Poison Quest

Rogues and poisons. Well, they do have talents labeled Assassination, so it seems perfectly natural, right? All a Rogue has to do is a little quest and she can apply poisons to her weapons. These poisons can slow movement, slow thinking (spell casting,) or do either instant damage or damage over time (DoT.)

For a complete walkthrough of these quests you can go here: Rogue Poison Quest, but the basics are below. The quest can be obtained at level 20. Alliance has it easy, Horde Rogues will need a buddy or two, or otherwise be able to handle a 23 Elite.

By the way, unlike the lockpicking quest, this quest is required to get the poison skill.

Horde -

1. Talk to the Rogue Trainer Shenthul, in Orgrimmar
2. He'll have you do the secret salute then give you a quest. Accept it.
3. Go to the Sludge Fens in the Northern Barrens, and find Fizzule
4. Use your flare gun, as instructed, and salute him.
5. He'll tell you what to do next.
   
6. Go to the tower just west of you
7. Pickpocket Foreman Silixiz at the base of the tower and get his key
8. Kill the guys you need to kill and go to the top of the tower.
   
9. Kill Gallywix (23 Elite) and open the chest. (You can pick the lock of that chest continuously if you want to work up your lockpicking skill.)
10. Dispell the poison affilcting you with an anti-venom (if you have one)
11. Go back to Shenthul and hand it in
12. He'll send you to Tarren Mills to finish up and get the poison dispelled.
    

Alliance -

1. The Alliance version is much easier that then Horde version.
   
2. Talk to Mathias, the leader of SI:7 in Stormwind. He’ll give you the quest Mathias and the Defias
3. Head to Westfall and go to the south east corner to talk to Agent Kearnan.
   
4. The agent is very trusting, so you don't need a special salute or anything.
5. You'll get the quest to enter the tower.
6. Pickpocket the guy at the base of the tower and head up.
   
7. Sap or kill Klaven at the top of the tower and open the chest (You'll be poisoned.) By the way, you can't continuously pick that lock. Just the one time is it.
   
8. Dispell the poison with an anti-venom and head back to Mathias. He'll give you your poison skill.
9. If you need to have the Touch of Zanzil dispelled he'll send you downstairs to the Doc.
   
10. Note that you don't have to kill anything to do this quest.
    

Congratulations, you're done. Now go kill something.
