Minecraft Dungeons:Conduit

The Conduit is an new consumable that appears in the Hidden Depths DLC that acts as a portable oxygen tank.

Obtaining
The Conduit can be obtained from Arena Battles dropping from certain pillars.

Usage
Conduits can be picked up similarly to TNT and can be used as a portable oxygen carrier instead of going to multiple bubble columns. They can also be placed on the ground and can be used as keys for certain doors. They can also grant the player Swiftness for an unlimited amount of time as long as the Conduit is with the player. If a player drops the conduit in multiplayer, other players can pick it up too.
