To make potions in Oblivion, you'll need to mix ingredients that share an effect using alchemy tools

. Here's how to make potions:

1. Acquire a Mortar and Pestle, which is essential for mixing ingredients. You can get one for free by joining the Mage's Guild or purchasing it from alchemy stores

2. Other tools that can improve your potions are the Calcinator, Alembic, and Retort, but they aren't required

3. To begin, open your inventory and use the Mortar and Pestle

. This will open the Alchemy window, and you can then select ingredients you want to combine

4. Choose at least two ingredients that have a common effect

. When you highlight an ingredient, the effects will be listed at the bottom left of the crafting menu

. For example, apples and beef both have the "Restore Fatigue" effect

5. Select the "Create" button to mix the ingredients and create the potion

. The potion will be added to your alchemy inventory

6. The potency of the potion will depend on your alchemy skill level

. As your alchemy skill increases, you'll have more options with ingredients
