Omega Arsenal

Every weapon is built from three new ores and five crafted components.

📡 Nemesis — orbital strike radio (Class Ω)

The Nemesis orbital battery

A military walkie-talkie: graphite casing, rubber grips, amber trim, radar screen, orange push-to-talk button and an antenna with a red LED. Right-click and a 10-second sequence plays out like an anime finisher:

1. You raise the radio: "Nemesis, this is <you>. Requesting an orbital strike."
2. Satellite view — a teal monochrome feed with scanlines: every enemy within 64 blocks is locked on, one by one.
3. A storm breaks out and, high in the sky, the orbital battery lights up: a ring of light with one platform per target, each one tracking its target with a red laser.
4. One beam per target: a column of light falls on each enemy wherever it is now (240 damage), with a black-and-white impact frame.
5. The platforms converge… "Fire." — the Nemesis Lance comes down: 900 damage, 32-block shockwave, 15-block crater with molten walls, light rays, a red 天罰 seal and a mushroom cloud.

You stay still and invulnerable during the call; the camera follows the scene, and other players see it all from the world. Up to 8 targets — monsters, mobs attacking you and other players, never villagers or animals. 45 s cooldown, 1,000 energy.

⛏ Tools — Voltium, Flux Crystal, Omegium

The fifteen tools

A sword, a pickaxe, an axe, a shovel and a hoe in each of the mod's three materials. They are real vanilla tools — stripping, paths, tilling, sword sweep, enchanting, anvil repair — and each series has its own power. Sneak to mine a single block.

• Voltium — Conduction: the electric arc follows whatever is connected, a few blocks per tick. The pickaxe breaks the whole ore vein (iron and deepslate iron together, up to 32 blocks), the axe fells the whole tree and its canopy rains down (a log cabin without natural leaves is left alone), the shovel empties a clay, gravel or sand deposit, the hoe harvests and replants the whole field. The sword's full-strength hits send an arc that jumps to the 3 nearest enemies — monsters only, never through walls.
• Flux Crystal — Resonance: every block mined in a row makes the crystal ring a higher note and the tool faster, up to twice as fast. Right-click the pickaxe: echo. A violet wave sweeps through the rock and every ore within 24 blocks lights up through the walls, each family in its own color, for 12 s (20 s cooldown). The sword hits 10 % harder with each blow in a row, and the fifth one shatters the crystal, hurting every enemy around the target.
• Omegium — Amplitude: pickaxe, axe, shovel and hoe work in 3 × 3 in the plane of the face you hit (chests and much harder blocks such as obsidian are left alone); the hoe tills and the shovel makes paths in 3 × 3 too. Right-click the sword: energy blade — a crescent of light flies 24 blocks forward, cuts through every enemy in its path (1.5 × the sword's damage, Sharpness included) and breaks on the first wall. Fireproof, like netherite.
• Recipes use vanilla shapes; the handle is a stick (Voltium), a Voltium ingot (Flux) or a Flux Crystal (Omegium) — each tier needs the previous one. Right-click powers never steal the off hand: a shield, food or a torch in your off hand keeps working.

🪐 Cosmos — planetary cannon (Class Ω+)

The Cosmos supernova

A long midnight-blue rifle with gold trim. Inside its open chamber spins a tiny solar system: the Sun and, in orbit, the planet loaded in the barrel.

• Tap right-click: planet shot. A rune portal opens at the muzzle and the next planet flies out — a real textured sphere spinning on its tilted axis, with its atmosphere (Saturn's rings, Uranus' rings, the Moon following the Earth). The eight planets fire in order, Mercury to Neptune, then the barrel starts over.
• Every planet hits differently: burning metal shards (Mercury, 160 damage), a molten-rock geyser (Venus, 220), an atmospheric blast (Earth, 260), rust-red dust (Mars, 240), a swirling storm over the crater (Jupiter, 480), rings shattering into an ice disc (Saturn, 420), ice shards that slow survivors (Uranus, 320), lightning (Neptune, 340). The crater walls match: magma and basalt, red terracotta, ice, blue ice. 350 energy per planet.
• Hold right-click for 3 s: planetary alignment. The chamber fills with all eight planets, a beam of light marks the target (up to 256 blocks), and a solar system forms in the sky 72 blocks above it — the Sun, the eight planets on their orbits, a nebula and a giant rune circle. The planets line up, break away one by one and fall around the target, blazing. Then the Sun comes down: supernova — rainbow shockwaves, a pillar of light, an aurora and a lingering nebula; 1,600 damage at the center, a 70-block shockwave, and a 20-block crater with rainbow walls (concrete and stained glass of every color, glowstone).
• 60 s alignment cooldown, stored in the weapon; planet shots still work during it. Energy 6,000.

☀ Helios — solar beam cannon (Class Ω)

The Helios beam splits a mountain in two

Carried on the shoulder with both hands.

• Hold right-click for 1.8 s: the three focusing rings spin up, the lens ignites… and at full power the beam fires on its own. Release before that and the shot is cancelled (no energy used).
• A 5-second beam, 11 blocks wide (18 at the end of its range) and 256 blocks long. It cuts straight through terrain, trees, houses, mountains and mobs. Only an unbreakable block (bedrock) on its axis can stop it.
• Too powerful for its wielder: while firing, the cannon rears up 70°. The beam starts level, so the trench is perfectly straight, then climbs faster and faster and slices through everything above. Your aim is dragged along: the mouse can't pull it back down, and you can only turn slowly (45°/s). You are pushed back, the camera shakes and the HUD warns ⚠ UNCONTROLLABLE RECOIL.
• 2,400 damage per second inside the beam (ignores vanilla armor and shields) and targets catch fire. Items, projectiles and falling blocks are vaporized, TNT is ignited. Radiant heat burns anything within 4 blocks of the beam (240 damage per second).
• The rock shatters along the trench, then its walls melt into magma, blackstone, basalt and obsidian. Fires break out, and the molten rock keeps glowing and smoking long after the shot.
• Fire it at the foot of a mountain: the beam pierces it, then rises and splits it in two, all the way to the summit.
• 35 s cooldown (the radiators open and glow red), energy 3,000 / 5,000.

☢ Annihilator — weapon of mass destruction (Class Ω)

Annihilator strike and mushroom cloud

• Hold right-click: a 5-second charge through five phases — IGNITION, BUILD-UP, ACCUMULATION, CONVERGENCE, CRITICAL MASS.
• At 100 %: TARGET LOCKED — flash, targeting laser and impact marker. Release to fire: an energy charge flies in a straight line (up to 400 blocks) and detonates.
• It wipes out a whole village: a crater 68 blocks wide, 1,200 damage at the center with falloff up to 80 blocks, then a blast up to 120 blocks that tears buildings and trees apart, throws hundreds of real blocks through the air, sets what still stands on fire, and splits the ground with eight lava fissures that erupt as the shockwave passes. The sky burns orange, ash falls, and a mushroom cloud rises over the crater.
• Kept in overcharge for more than 4 s, it fires on its own. Release before 100 % to cancel.
• 20 s cooldown, energy 1,000 / 3,000.

◉ Oblivion — singularity generator (Class Ω+)

Oblivion singularity

Everything works with right-clicks, no holding:

1. Launch the graviton seed: it flies in an arc (about 100 blocks on flat ground).
2. Right-click while it flies: a singularity opens where the seed is (otherwise on its first impact, or after 6 s).
3. It grows for 10 s, up to 30 blocks in radius. Every block that enters the sphere disappears. Mobs, items and players are pulled in a spiral from up to 80 blocks away; past the point of no return, you fall toward the center. Inside the sphere: 300 damage per second. The sky darkens and light bends around the event horizon (gravitational lensing) while the accretion disk spins.
4. Right-click again: COLLAPSE. A gravitational wave sweeps 120 blocks (600 damage at the center), followed by gravitational crush (heavy gravity, no jumping) for 10 s. The crater walls fuse into blackstone, obsidian, crying obsidian, basalt and magma.

45 s cooldown, energy 2,500 / 4,000. The shooter, teammates and tamed animals are never pulled or hurt.

⬡ AEGIS armor — containment armor (Class Ω)

AEGIS armor

Upgrade netherite armor at the smithing table. Each piece stops part of the damage of Ω weapons, and the full set lets you survive them:

• Containment shield (600 points): absorbs what is left of Ω weapons, explosions and fire before your health, and recharges (50 points/s) after 4 s without impact. Every hit shows as a hexagonal bubble.
• Gravitational anchoring: never pulled by singularities, knockback reduced to 25 %.
• Stabilizers: no energy burn, crush, slowness, nausea or fire from Ω weapons.
• Shock absorbers: no fall damage.
• Shield gauge above the armor bar, visor brackets, and energy lines that glow in the dark and turn amber, then red, as the shield weakens. The chestplate sleeve covers your arm in first person.
• 24 armor points, 16 toughness, 0.6 knockback resistance, durability multiplier 45 (netherite: 37), fireproof, enchantable.

In full AEGIS you survive an Annihilator strike, an Oblivion singularity and a pass of the Helios beam — but a sustained bombardment will break the shield.

⛏ Ores, materials and crafting

• Ore veins glow in the dark. Flux Crystal resonates when touched (light, chime, reflections), Voltium crackles, Omegium hums.
• Smelt the ores into ingots and craft five components — Voltium Coil, Flux Cell, Focusing Lens, Omegium Plating, Annihilation Core — then the weapons. The Helios also needs a Solar Core and a beacon; the Oblivion needs a Singularity Core (echo shards) and a heavy core; the Cosmos needs a Stellar Core (eyes of ender) and a nether star; the Nemesis needs an Orbital Uplink Core (lightning rods and eyes of ender).
• Recipes unlock in the recipe book as soon as you pick up their key ingredient, show up in JEI / REI / EMI, and can be changed with a datapack. Conventional c: tags keep the ores and ingots compatible with other mods.

⚙ Features

• Animated 3D weapon models, first- and third-person poses (the Helios sits on your shoulder), custom sounds, HUD and dynamic camera (shake, flash, FOV).
