Question about Imbilicus immortalis

I use Umbilicus immortalis belt. Unfortunately, game doesn't show flask effects on minions in "character" sheet (I checked with increased rarity flask).

So, do "increased flask effect duration" passive nodes affect my minions using Umbilicus immortalis? How to find out flask effect duration on minions? Help please.

I would think they do. I don't know for certain but I think how it works is you are using the flask, buffs apply, then all the effects go onto the minions.

Trying to think if any of the effects could be be visualized. People usually come up with clever ways off testing these things if you want to know for certain.

I don't see anything preventing this from being the case though.
