Potion Craft: Alchemist Simulator

You will need the buy the Oil Potion base for this, both as the objective and to access the other effects more easily for serving customers. Do this early if possible, as you will have to turn away customers when they ask for the effects and that will make the rep grind worse and make you less money to build your ingredient supplies/get alchemy recipes and parts.

Buy Potion Base: Oil - Purchase from the Wizard NPC when he visits after beating Chapter V. This will be 8k base, so a Medium Haggle will take it down to around 6k.

Create Albedo - The recipe is unlocked by making Nigredo, which you must have already done for earlier chapters. Check my solution for its own achievement if you need to.

Reach a popularity level of 8 - This comes to grinding serving customers. Try and fulfill extra requests when you can, as you get +1 for each one you do. Some of them are easy, like "use at least one/half of X ingredient" as this can be thrown in after using a recipe to get what they want, or "Must be a strong potion" as you should have lots of Tier 3 recipes anyway. Ignore ones that are too expensive or time consuming, especially if they are optional.

Create Potion of Poison Protection - Can be found on the Oil Map (change base from Water to Oil at the top right of the potion screen) going down and right, shortly under Wild Growth. This is also present on the Water Map at a similar angle from the origin, but requires using a path into the outer ring through the bones, or crystals to skip over it.

Create Potion of Lightning Protection - Can be found on the Oil Map (change base from Water to Oil at the top right of the potion screen) going almost straight down, shortly down and to the right of Gluing. This is also present on the Water Map at a similar angle from the origin, but requires using a path into the outer ring through the bones, or crystals to skip over it.

Create Potion of Fire Protection - Can be found on the Oil Map (change base from Water to Oil at the top right of the potion screen) going right, shortly up and right of Lubrication. This is also present on the Water Map at a similar angle from the origin, but requires using a path into the outer ring through the bones, or crystals to skip over it.

Create Potion of Frost Protection - Can be found on the Oil Map (change base from Water to Oil at the top right of the potion screen) going almost straight left, shortly down and left of Light. This is also present on the Water Map at a similar angle from the origin, but requires using a path into the outer ring through the bones, or crystals to skip over it.

Create Potion of Gluing - Can be found on the Oil Map (change base from Water to Oil at the top right of the potion screen) going almost straight down and a little left, or up and right from Lightning Protection. This is also present on the Water Map, where it is down and right a way from Lightning Protection, but this is much further away and requires careful navigation through the bones or crystal use.

Create Potion of Slipperiness - Can be found on the Oil Map (change base from Water to Oil at the top right of the potion screen) going right, shortly under and left of Fire Protection. This is also present on the Water Map, where it is down and right a way from Fire Protection, but this is much further away and requires careful navigation through the bones or crystal use.

Create Potion of Stench - Can be found on the Oil Map (change base from Water to Oil at the top right of the potion screen) going down and left at about 45 degrees, almost straight left of Gluing. This is also present on the Water Map at a similar angle from the origin, but requires using a path into the outer ring through the bones, or crystals to skip over it. This one is even worse, as it is behind the little bulge that has Necromancy in, making Crystals much preferred if to reach it.
