18w14a added the new "Slow Falling" effect, which is obtainable as a brewable potion, so it should now be an effect that you need to attain in order to get the "A Furious Cocktail" and "How Did We Get Here" advancements, however the advancement files for 18w14a have not been updated with this.
On a side note, as Potions of the Turtle Master give Resistance, Resistance should also be added to "A Furious Cocktail."

I created MC-128463 for it.
The "Conduit Power" effect was added in 18w15a, and I'd imagine this is another effect that should be added to "How Did We Get Here." Should this report be re-opened or should I post a new report?
