i have like two points in it and am running around in the last arc opening every container i see (including stuff like rows of books). i've had it proc several times, sometimes a few in the same building or area
i agree with the above post in that it's competing with persuasion on your party leader. i may find myself picking it up earlier than i did on this run in future runs because it seems really good, and i like the style of play (searching every corner) it promotes. i now look through barrels in crates in the off chance i'll find something that i can at least sell for a good amount when i wouldn't have before, and especially earlier on in the game when money is much more difficult to come by and min/maxing becomes more and more necessary on higher difficulties. you certainly don't need it, but it's helpful and adds a little flavour to the duller parts of the game
