Question about potion duration increases from alchemy tree

[Captain Australia]

If I have three alchemy skills slotted (each one capped out saying it increases potion duration time by 25%) my assumption is that I should see a collective increase in potion duration of 75%

If that, for example, applied to swallow, I'd be pleased .. but I checked some potions, with the alchemy skill slotted and unslotted ...

Swallow - 20s duration
Cat - 240s duration

No change regardless whether I have the alchemy skills slotted (at the moment just have heightened tolerance & acquired tolerance - but interested in the mechanic)

Shouldn't slotting alchemy skills be increasing the overall duration of potions like Cat ?

I noticed this same thing but I didn't actually see a change in potion durations until I slotted 2 alchemy abilities + a greater green mutagen. Once I did that my Swallow duration jumped slightly to 25-ish seconds and decoctions went from 35 to 45 minutes.

I would suggest using a greater green mutagen and seeing what happens.

Thanks mate, I actually have that - so slotting & unslotting increases the vitality bonus due to the green adjacency .. so you get a nice vitality boost .. but I don't see any impact on the potion durations.

Skills are definitely slotted, at the moment just two of them, one deliverying 25% and the other 15%, so it should total to a 40% increase in potion duration.

But when I suss our Cat (nice to test because it has a longer duration), without any slotted, it's 240 seconds .. and when I slot the green skills it remains unchanged at 240 seconds.

Dunno, just puzzled - without this benefit I'd probably forego green and focus on the power bonus & combat skills of red

Yeah I'm not sure what's going on then. I'm spending points on alchemy abilities last and only have 2 of them maxed out right now but it did make the slight difference above when I did a test and slotted them with a mutagen.

Maybe the abilities that are slotted matter. I have Heightened Tolerance and Acquired Tolerance maxed out and slotted.

I just did a test and my Swallow is 30 seconds with these 2 things slotted + a greater green mutagen. The potion description never changes if that's what you're looking at, it'll always say 20 seconds for Swallow. But when you actually use a potion the duration timer will reflect the improved duration.

[Strandly]

Superior Cat lasts 18 minutes for me now so yeah it works, you simply have to use the potions to see the change.

[Captain Australia]

Oh okay, hey man - thank you.

So the tool-tip, potion description is what's leading me astray.

I expected those numbers to change. If they're static (but when you quaff the potion the ACTUAL duration is increased), I'm jiggy.

Thanks for the schooling, mate.

[Strandly]

Yep.
