VoidBloom

Exploration: ruins, an obelisk, a camp, an underground vault, an echo village, and an arena with mob waves. Explorer maps in loot chests (and from echo cartographers) lead to the structures. Mobs and boss: new mobs with custom models and glowing details, plus the Echo Sovereign boss with two phases. Ores and gear: a new ore in each world (Overworld, Nether, End). Smelt them together in the multiblock Resonance Forge, which has a furnace-style GUI. The result is resonite, which beats netherite. You can upgrade netherite gear with it and add armor trims. Mechanics: echo tools and armor with special abilities, plus echo wood blocks, new food, and echo-beet farming. Travel and redstone: Echo Gates let you name your own gates and teleport between them. There are also redstone devices: a proximity detector, a metronome, a wireless transmitter and receiver, and a launch pad.
