You can find Nightshade in The Elder Scrolls IV: Oblivion at several key locations:
- Southwest of Skingrad near Fat Ramp Camp : This area has a good number of Nightshade plants growing around the camp, making it a reliable place to gather them
- The Main Ingredient shop in the Imperial City Market District : You can purchase Nightshade from Ogier Georick here, who sells four Nightshades for 8 gold
- Frostcrag Spire : After purchasing the garden for Frostcrag Spire, you can harvest several Nightshade plants there. These regrow every three in-game days, allowing for repeated harvesting
- West Weald region and around the road west of Skingrad : These wilderness areas have numerous Nightshade plants scattered throughout
- Arcane University : Nightshade plants can be found growing in the alcoves around the ring at the Arcane University
- Priory of the Nine southeast of Skingrad : This location has many Nightshade plants and is accessible early in the game
Nightshade plants regrow every three days, so you can return to these locations after waiting or sleeping to harvest more. Additionally, some alchemy vendors and loot chests may have Nightshade in their inventories
. These locations are useful especially if you need Nightshade for quests like curing vampirism or for Mephala’s Daedric quest, or for alchemy purposes
. In summary, the most accessible and reliable places to find Nightshade are near Skingrad (especially southwest near Fat Ramp Camp), The Main Ingredient shop in the Imperial City, Frostcrag Spire garden, and the Priory of the Nine southeast of Skingrad
