Everything under alchemy needs only be crafted once. Look at alchemy like gear: bombs, potions, and oils. Once you have a recipe and craft them they're yours forever, though have limited uses, and every time you meditate you'll use one bottle of alcohol to refill all that have been spent. You can then acquire additional recipes to craft upgrades to already crafted alchemy. So Swallow -> Enhanced Swallow. But yeah, craft once, yours forever, refill by meditating.
oh thats awesome, so I definately should craft whatever I can then
