The problem isn't the amount of barrels. The problem is that there seem to be to many poison, flammable and water barrels. They need to make some of the barrels be just barrels, barrels with loot in them or just plain barrel mimics.
A group of DnD players walk into a bar
The bartender asks, “what’re you all in for?”
The group says “we’re hunting mimics”
The bartender laughed, the group laughed, the table laughed. They killed the table.
I do want the elemental effects, but the barrels need to be plain barrels. Or water barrels. Barrels usually hold ale or water. Not poisonous gas.
