Ingun's Supply Chest Key

Awarded to player after they find 20 deathbell, 20 nightshade, and 20 nirnroot for Ingun Black-Briar. It unlocks a chest full of random ingredients and potions in the back of Elgrim's Elixers in Riften. The chest restocks after 24/48 hours, but the player must leave the store before hand.
