Return to Chillwind Camp

You fill the bottle with enough of the cauldron's poisonous concoction for a suitable sample to be studied. With the poison in hand, it is time to return to High Priestess MacDonnell at Chillwind Camp to complete the mission.

Well done <name> - it should take Alchemist Arbington no time at all to analyze this and devise a counter agent to introduce into the cauldron. If we are able to pump out enough of it into the air, we might be able to weaken all the Scourge present here. This will no doubt be an ongoing ordeal; we will need to continually hit these cauldrons and introduce our reagents into their mix. Still, if we can keep it up, we will have a huge advantage over Scourge when the time comes for battle!

You carefully fill the bottle with enough of the cauldron's ichors for what you consider to be suitably sized sample. With the poison in hand, it is time to return to High Priestess MacDonnell at Chillwind Camp to complete the mission.

Ah, there is plenty in here for study. Well done, <name>! For now, the next step is in our hands. We'll need to produce a list of reagents that, when combined with what is already in the cauldron, will act as its counter. The only way we will be able to introduce this is by placing the reagents into the cauldron directly. Alchemist Arbington will have more information on that, so be sure to speak with him at your earliest convenience.

You delicately top off the empty bottle; a sample of the foul substance that churns under the platform of the cauldron now oozes back and forth inside the fragile glass container. With the poison in hand, it is time to return to High Priestess MacDonnell at Chillwind Camp to complete the mission.

Another finely executed mission, <name>! This makes three cauldrons available to us to turn against the Scourge. If Kel'Thuzad's necromantic dominance over these lands wasn't as strong as it currently is, I'd dare say you'd shut them down completely! Alchemist Arbington will have a report on what this cauldron - as well as the other cauldrons subverted - will require to deliver our counter agent to the plague. With that, the time has come to bring the last cauldron of the west under our influence!

You carefully close the spigot in the control panel, watching the cauldron's putrid ichors drip into the empty bottle. With the poison in hand, it is time to return to High Priestess MacDonnell at Chillwind Camp to complete the mission.

Congratulations <name>, you've unlocked the last cauldron for us! Alchemist Arbington will soon know what this cauldron requires as far as reagents needed for the mix. As for you, I am sure that Commander Valorfist will want to thank you personally for the assistance you've given us. Without you, our struggle against the Scourge would have been nearly insurmountable. Thank you, hero!
