|(Alchemist) Prepare Potion Lv. 5, (Biochemist) Alchemy Lv. 2|
Combine many different potions to create new potions. You can create potions that weigh less, but have the same effectiveness, or create heavier potions that heal for far more. For potions that summon creatures to attack, they might have a better attack rate, or have a new skill to use.
