Deep Caverns

The Deep Caverns are a mining area accessed from the Gold Mine where players can collect traditional mining resources as well as obtain rare items. Obtainable resources include coal, stone, iron, lapis, redstone, emeralds, diamonds, obsidian, gunpowder, rotten flesh, bones, and rare drops from the various enemies.

The Deep Caverns is unlocked when the player has reached Mining level 5. It can also be accessed directly by a Deep Caverns Portal on a player's Private Island. The deep caverns travel scroll will add the Deep Caverns to the warp menu, but this requires the VIP+ rank.

Locations
The Deep Caverns is divided into 6 layers (excluding Dwarven Mines) that are progressively more dangerous the deeper players travel. After discovering them for the first time, they can be quickly traveled to from the Lift Operator's elevator shaft.

Each mine has its own resources and its own hostile mobs, each increasing in difficulty as the player progresses deeper into the caverns.

In all levels, it is possible for Mobs to spawn next to, or even above players, causing harm to the player with no chance to defend against the attack. This is especially problematic in the lower levels, as the Miner Zombies and Larger Emerald Slimes can deal an absurd amount of contact damage in the early game.

Trivia

 * There is currently a bug where if you jump into the void near the portal and hug the wall, you will instantly unlock all the sub-mines.
 * The transition sections between levels will not spawn mobs from either floor and prevents those mobs from entering said sections. This is commonly exploited, as the transition section between the Diamond Reserve and Obsidian Sanctuary allows players to easily and safely mine high quantities of diamonds.
 * Travelling to the Deep Caverns without using a Launch Pad will result in the Lapis Quarry being blocked off.
 * The Lift is gone, meaning that you can fall down into a previously inaccessible area. However, much like the entrance to the Lapis Quarry, it is blocked off.
