While in Svartrau, I met a young uriashi girl named Ocha. She was far from home and in the middle of something really dangerous. So of course I got entangled in this whole mess...
Bring the right memento for Ocha’s spell
You can start Ocha’s quest at the Altenmarkt tavern even without A Mother’s Plea. If you follow the spell route, the correct memento is Andrei’s Ring, found in a small chest on a desk in his hideout.
The hideout contains other personal items. If you collect several, identify the ring when Ocha asks what you found. Her later riverside conversation concerns whether she stays among humans or returns home; it is separate from Coen’s romance options.
The item name matters because Andrei’s Pendant is a different memento with its own page. Use the ring entry when the objective asks for the object used in the spell, and keep the pendant as a separate collection record.
After the spell, the conversation can be followed from the riverside marker or from the quest links on Ocha’s character page. The Elder’s request provides context for the village, but it is not required to begin Ocha’s personal problem.
