The Oracle has the same item as the prize in Sokoban, so you can pay her to tell you what the prize is (because she’ll have it with her). This opens up a strategic choice where players can decide whether to kill her and skip Sokoban, or not. She will need to be quite stronger than her current abilities are, with passive attacks that work even at range. Alternatively, she could carry the other Sokoban item, depending on how formidable she is.
