"The trial chamber is a structure packed with new adventures and filled with traps, trial spawners, mobs, and (as an extra bonus) treasure! Trial chambers are procedurally generated, which means you’ll face a new challenge every time you venture into them, and find something different behind each door! Explore deeper and deeper and you might find yourself stumbling across resources that’ll help you, or mobs that’ll hinder you. The trial chambers are also home to a playful (and dangerous) hostile mob: the breeze!"

Trial Chambers seem just like what Minecraft needs which is more dungeoning adventures added to the base game. That said, I'm curious how it will work and will you discover these randomly in your world or create a new Trial Dungeon world? Either way, looking forward to delving deeper!
