List of possible consumable items to be locked include but not limited to Potions, Food, Recipes, Motifs, and Master Writs. By locking a Consumable item it no longer shows up at the Vendor to be sold for the entire stack. Consumables not applied to your Quickslots will give a confirmation pop up that you want to use that item, items that are already in your Quickslot such as Food and Potions will skip the confirmation pop up and still use immediately.
