Morrowind Alchemy Potion FAQ:
Alchemy Equipment
There are 4 types of equipment that are used in creating Alchemy potions.
(Descriptions are from the manual)
1: Mortar and Pestle- Required to mix a potion, and determins the
initial potion strength.
2: Retort - Increases the magnitude and duration of all
positive effects in a potion.
3: Alembic - Decreases the magnitude and duration of all
negitive effects in a potion.
4: Calcinator - Increases the magnitude and duration of all
effects in a potion
Note: you only need the Mortar and pestle, the other items just
increase the effectiveness of the potion.
There are also different levels of Quality of these items, they are:
1: Apprentice
2: Journeyman
3: Master
4: Grandmaster
5: SecretMaster
The higher the quality of the apparatus the more it effects the
outcome of your potion.

to look into the X-Box one - provided the X-Box version is not different
