Enriched snapdragon

Enriched snapdragon is a While Guthix Sleeps quest item obtained by harvesting a grown enriched snapdragon seed from the special herb patch on top of White Knights' Castle. Harvesting it has no Farming requirement, though starting the quest requires 65 Farming (can be boosted).

Using it on Truth serum turns it into a Super truth serum, which is needed during the While Guthix Sleeps quest.
