How to unlock the Another sip? achievement in GreedFall - Definitive Guide
SAVE YOUR GAME. This way you can load it back up after popping the achievement and keep al your potions.
Once you get to the island of Teer Fradee you should have a good amount of potions in your inventory already. Hit and scroll over to Potions. Press on the first potion to drink and then continue to spam + until you have drank everything in your inventory.
Next, head to the merchant in the Copper District. Sell everything in your inventory to the merchant and then buy all the health potions and magic potions you can from him. I think he had 8 each in my game. If you have any gold left over, buy as much of the cheapest potion available that you can. Now spam drink everything you just bought and it should be enough to hit the 50 mark and pop your achievement.
Now you can reload your save and continue on as normal.
You can buy potions from merchants and find them as loot while exploring as well as crafting them from the workbench with the correct ingredients. The potions have various uses, as per all RPG games, there are regeneration potions such as health, magic and armour potions as well as potions that buff you and/or your attacks. When playing on the easier difficulties, they may feel largely unnecessary so feel free to bind one to a button and keep using it to grind this out. It's likely however if you are a magic using character that you will use the magic potions a lot, or otherwise when playing on Extreme you are likely to use a lot of health potions, so it won't be strictly necessary to grind.
