Witch Kalis:
Tell me, how does the poison taste? Everything growing dark, is it? That would be death coming for you. I fear that soon we will need to add another grave here... Will your comrades find and bring back all the ingredients in time?
Oh, I do hate to see you in such pain. Would you care for some hints?
Herb of Vanor can be obtained from vanor silenos. Herb of Harit can be obtained from harit lizardmen. Herb of ol mahum can be obtained from ol mahums. The Shamans will have the herbs.
In order to obtain the Blood of Eva, you must visit Witch Athrea. She is my younger sister. Some time ago she left for Hardin's Academy to meet with Grand Magus Hardin.
Remember that when your clan members bring back all the ingredients, you must gather them up and bring them to me. I will create the Antidote for you.
