Minecraft Dungeons:Bubble Column



Bubble Columns are new underwater structures that will appear in the Hidden Depths DLC. They appeared in two official Twitter videos along with a Drowned holding a Trident in the first, and a Coral Skeleton and Tropical Slime in the second.

Usage
It is possible that these columns will act as oxygen refill spots for players, giving free oxygen for them to progress the underwater levels. Being a refill spot, they could possibly damage certain aquatic mobs when close to them, other than this, not much is known about their true function.
