I found this when looking this up
https://www.reddit.com/r/BaldursGate3/comments/j6se0n/tips_and_tricks_discovered_so_far_ea_spoilers/If a potion is thrown and characters stay close enough then the effect is applied to everyone in the area, so a minor health potion can become a superior etc.
The hags potions don't work
flight doesnt
oil of sharpness doesn't
poison flasks aply poison but not to the weapon
hill giant strength works
healing works
haste works
invisibility works
resistance potions work
animal speaking works as well
sleeping potions work
some poison flasks can cause some serious harm. the ones of which you only have 1 at the end of a run
The healing mist on the floor suggests that it is intended and if the effect can be spread it would be fine. If you run into the mist then only one person gets the benefit.
Preparing lots of healing pads might looks strange. It does not have a timer it seems like.
In general though, the ability to target alchemist fire, void bombs, sleeping potions etc is fantastic. It is way more realistic to sneakily place alchemist fire among the goblins than hurl large barrels everywhere.
Would be awsome to target the alchemist fire dangling on a golin's belt and have them explode!
have a good one
