A Better Ingredient

It is as I feared -- the toxin is simply too weak for such a powerful creature.

If we are to create a toxin of high enough potency, you must venture to the bottom of the Temple of Atal'Hakkar, unlock the secrets of the altar and recover a putrid vine from the guardian there. The temple is dangerous, and it would behoove you to bring friends.

Return to me when this is done.

Have you recovered the vine?

At last, the toxin can be created in full. I dare not require you to inflict it upon the creature again, as I have asked too much already.

You have my thanks and respect. May you be well in your travels, <name>.
