Curse of the Calamity adds three bosses, each tied to a world event that spreads a curse across the Overworld, plus a new dimension called the Abyss where you can flip your gravity and walk on ceilings.
Minecraft 1.21.1, Fabric.
Each boss lives in its own dimension and has a matching hazard that can appear in the Overworld.
Vaelen, the Corrupted (Nether). A fast melee boss with a giant scythe. Uses leaps, ground slams, combos, and a parry-stun mechanic. Its curse, the Corrupted Wastes, spreads flora infection and wears down armor. Drops Vaelen's Scythe.
Vulturnus, the Stormbringer (End). A large serpentine storm dragon that creates vortexes, calls down lightning, and pushes players around with strong gusts. Its curse brings Tempest Storms, with supercells and roaming tornadoes. Drops the Tempest Greatbow.
Bellatrix, Empress of the Abyss (The Abyss). A three-phase fight against a cosmic entity. She summons constellations, opens black holes that bend the screen, and dashes between floating islands. Her curse causes meteor showers. Drops the Empress's Stargazer, a staff.
When a boss awakens, its curse starts to leak into the Overworld. Around ancient altars, a hazard zone grows over time, changing biomes, corrupting blocks, and affecting players inside it. It stops when you cleanse it or kill the boss.
The Astral Gateway takes you to the Abyss, a dimension of floating structures over open space filled with stars. Inside the ancient sanctuaries you can eat Abyssal Fruit to invert your own gravity, which lets you walk on ceilings and explore ruins upside down.
All weapons have custom player animations.
Abyssal Logs can be crafted into planks, stairs, and slabs. They use the vanilla tags (#minecraft:planks, #minecraft:wooden_stairs, #minecraft:wooden_slabs), so they work in recipes for crafting tables, sticks, chests, and wooden tools.
Boss music is analyzed in real time, and shockwaves, sky pulses, and arena effects follow the beat. The mod also adds a black hole lensing effect, a screen-shatter animation, and custom skyboxes.
