Why barrels anyway? Its like a bad Hobbit joke or something. I could see it working thematically in specific areas, like blowing up a distillery, or maybe at the docks knocking over barrels of fish to go full monger, whatever. I don't remember that chapter in Conan, but sure. Having barrels and chests to hurl about constantly just seems silly though. Maybe it would feel more realistic if you could interact with barrels, knocking over a barrel and rolling it towards someone. The same way you could maybe roll a boulder down the hill for a clutch goblin flattening. Picking up a small to medium sized rock or object to throw is alright I guess. But carting around barrels for combat like a literal mule is weird.
I don't mind the idea of shit like barrels getting jostled around in combat, but it should work more like a "Shove" action, not a "Throw" action.
You should be able shove a barrel or big rock or crazy nautiloid tank, maybe launch it a short distance for big damage like a raging circus strongman, but only in the area where combat is going down. Not like pocketing them for later.
The caustic bulb seems alright to throw since its pretty alien anyway, flask of acid or lamp of oil, ok. But barrels? For the big hits it could just as easily be an occasional magic rod with similar exploding environmental effects couldn't it? Or case of strange Gnome grenades. Some other more limited items or artifacts that make sense for high fantasy.
