I never got the level-up multiplier system, or rather, I understood completely it once but not anymore. The basic idea is tat you get attribute multipliers depending on what skills you've increased to level-up. Many skill increases in strength dependend skills give multipliers in strength.

To mix potions, buy/steal/find a mortar and pestle and simply select it and drag it to your character paperdoll in the inventory screen. A new box should appear where you can select which ingredients to mix, select your alchemic equipment as well as naming your potion. There are three other alchemic tools in addition to the mortar and pestle:

*Retort - increases the magnitude and duration of all positive effects.
*Alembic - decreases the magnutide and duration of all negative effects
*Calcinator - Increases the effect and duration of all effects.

The three above is optional but you always need a mortar and pestle to mix potions. Your success rate in mixing potions depends on your Alchemy skill and your Luck.
