Description of the problem

How to reproduce:

1 Find an infusion recipe to make
2 Get the appropriate vials of essence to make it
3 Put the vials of essence into a water filled infuser (the amount of essences doesn't seem to matter)
4 Stir the infuser until it gives an audio cue and changes color
5 Shift right-click the infuser with a bucket, and pour it into an alembic
6 Let the alembic finish processing the infusion
7 Retrieve the infusion with a dentrothyst vial
8 Watch in despair as you get infusions with potency 1, duration 1, regardless of what you do.

Expected result:

I should get an infusion with potency and duration which match the amount of essence I used. For example, when I try to make a healing elixir, I use 3 yeowynn and 3 ordaniis, and I should be getting a healing elixir with potency of 3, duration of 3.

Actual result:

Regardless of how much essence I use, and regardless of the ratios, I seem to only get infusions with potency 1, duration 1.

Unable to replicate...

You need to use 3 full vials of Yeowynn and 3 full vials of Ordaniis if you want to max out the stats. A full vials holds 5 of an aspect amount. Fill 3 vials of each to 5 aspect value and try them.

The potency and duration is calculated from the ratios of the contained aspects. It's not ideal right now and I'd like to change and rebalance it at some point

Oh ratio^^ I was like... lately for a Brew of the Cat eye, I've used 12.0 of Dayuniis, with 1.0 of Ordaniis. The two others Freiwynn, and Geoliirgaz was also at 1.0. Result Lv I/II (or 2.25) Potion last 4:40 instead of 2:30.
If I want to increase potion potently without using more than 15.0 Dayuniis, would it help if others elements was at 5.0? I know that more secondary product I use, more potions per bucket I could recover... Once I've earned 12 Potion Lv 1/1

For now the most efficient recipe for a night vision potion is 0.11 in every stats as it lend a minimum potion effect with 1 potion per buckets.

Same issue here: I used 1 vial of 5.0 yeowynn and 1 vial of 1.0 ordaniis. expected healing 5 with some small effect duration but i recieve tier 1 potency and tier 1 duration

Duration and potency are based on the amount of full vials/multiples of 5.0 aspect. A vial of 5.0 amounts to a one level change in potency/duration, but note that smaller amounts still have an effect on duration (but not potency, it seems). Closing because it was a misunderstanding of how herblore works.
