Medieval Kleinstadt
Obtain angelica. (Angelica can be found in the Locksley Estate in Sherwood, the Abbot's garden in the St. Denis Abbey, or A Small Path next to a Creek in Tara.) Go to Kleinstadt and find the apotheker. ASK APOTHEKER WELLNESS. He will ask you to bring an angelica plant to him. GIVE ANGELICA APOTHEKER. You learn DRVA!
