Abyssal&Descent

The mod adds the Abyss, a custom dimension filled with ancient ruins, unique creatures and large-scale boss battles. Players reach it by breaking through bedrock, which requires the Abyssal Resonance Pickaxe. That tool needs about 20 seconds per block and destroys only three bedrock blocks, so the opening is a deliberate task. Once inside, the Abyss is split into four regions, including the Silent Wastes and the Rift Highlands, and each has its own terrain, atmosphere, structures and creature distribution.

The content centers on equipment progression and exploration. Abyssal Relic Ore sits in the deepest layers of the Overworld. Smelting it yields Abyssal Core Fragments, and nine fragments combine into an Abyssal Core that is used for crafting. The Abyssal Chestplate protects against void damage. The mod also adds new exploration content to the Overworld and changes the world-generation of existing worlds with custom dimension structures, so backing up a world before installing or updating is advised.
