Halloween ModJam

Spore Creepers adds fungal spore mechanics: when creepers burst they release a harmless spore cloud that can slow and infect nearby creatures and let you become a drifting spore that can latch onto and control zombies, creepers, villagers, or other players. While possessed you control the host’s movement, view, jumps and attacks (you can ignite a possessed creeper and, after holding a player for 60 seconds, take permanent control), hosts keep normal physics and immediately resume normal behavior when possession ends, and if you relog you’ll return in spore form but must manually latch onto a new host—there is no automatic reattachment to your previous host.

The Boltbound Grimoire is an enchanted book filled with 50 unique spells in six categories—Elemental, Shapeshifting, Teleportation, Force, Movement, and Utility—all unlocked the moment you obtain it. Simply right-click to open the spell menu, then click any spell icon to cast that ability (each has its own cooldown). From summoning fireballs and lightning bolts to shape-shifting into creatures, teleporting across distances, manipulating force fields, granting flight, and more, the grimoire lets you wield arcane power in survival Minecraft without the need for additional unlocks.

Reaper’s Scythe is a one‑handed weapon: left‑click to melee (about 5 total damage) and right‑click to fire a long Witchfire Beam. The beam reaches 32 blocks, deals 20 damage, applies Burning (~4s) and Wither I (5s) on hit, costs 1 energy and triggers a 5s cooldown, and now shows denser ghastly green particles and a larger impact burst; a beam kill on a hostile instantly refills all energy and clears the cooldown with a faint green aura and pulse sound (fire‑immune mobs won’t burn but still take damage and Wither). While held your vertical energy meter appears on the right side of the screen, and melee still has a slightly extended late‑swing reach (~4.5 blocks) that produces a green wisp trail and deeper impact sound when those long hits connect.

When a zombie, husk, drowned, zombie villager, or special Dormant Infected(was the placeholder entity so it doesn't have anything different from a regular zombie now that it can also infect you but i decided to not ask for the AI to remove it) slays you, you become a zombie instead of dying, when becoming a zombie you can't control your character anymore. There are currently 2 ways to become human again: 1:Getting cured by another player(the same way villagers get cured, takes some time, there isn't any shaking visual effect and the golden apple doesn't disappear but i'm out of credits so i can't do anything but it still works after you wait some time) 2:Dying and respawning

The Zombie Apocalypse come true, this mod will make everything gone exept urself and nonstop amount of zombies! will you survive or will you join them?

The Crimson Trophy Chainsaw is a netherite-tier melee weapon that constantly glows crimson, guarantees trophy-head drops on kills, and splatters gore with immersive rev/engine/impact sounds. Left-click swings deal base melee damage and charge a 100-point power bar—each hit grants +15 power and hitting multiple different enemies in quick succession (~0.4s) awards an extra +5 for each new unique target (so sweeping multiple foes now properly grants power per enemy; repeated hits on the same target don’t give the bonus). Hold right-click to rev and channel a damage-over-time beam up to ~3.5 blocks (about 5 damage/tick) that consumes 2 power per tick and requires at least 1 power to start; releasing right-click stops the beam and the chainsaw won’t gain power while channeling.

This mod adds the Witch Creeper Plague, a creeper dressed in witch clothing that brings a terrifying twist to the classic explosive mob. When this special creeper detonates near the player, it unleashes a plague effect that transforms all nearby mobs within a 6-block radius into regular creepers, turning peaceful animals and villagers into dangerous explosives. The Witch Creeper Plague behaves like a normal creeper—hissing, approaching players, and fleeing when struck—but its explosion creates a cascading threat that can quickly turn a safe area into a creeper-infested danger zone.

A mysterious book that allows players to write the name of any mob or player within its pages, causing them to perish instantly. (As instant as 0.8 seconds and can choose the base name like "Cow" instead of the dumb id. I hate id inputting.)

This sinister jack-o-lantern emits an eerie glow while cursing all players within 15 blocks of it. Once placed, it periodically afflicts nearby players with haunting whispers in chat, visual screen flickering through the Darkness effect, and debilitating status effects including Blindness and Slowness. On rare occasions, it will even summon zombies near cursed players, announced by the ominous message "You hear a groan nearby..." The curse activates automatically when players are in range—simply place the block to begin spreading its malevolent influence, or break it to end the haunting.

The Butcher’s Cleaver is a cursed, oversized melee weapon that grows stronger as you kill hostile mobs: it gains up to 20 Blood Charges (each +0.5 damage, decays after 2 minutes of no kills) and grants Strength I at 10 charges and Strength II at 20, plus extra meat from animals and a hidden Bloodlust curse that gives burst damage/speed with a hunger/Wither drawback after rapid kills. Use it like a weapon—left‑click to swing, right‑click to perform the wide 5‑block Meat Reaper attack (costs 4 charges, 10s cooldown), and hold Sneak (Shift) to run Reaper’s Revenge (uses 10 charges; bleeds nearby mobs for 2 damage/sec while you hold it for up to 10s, heals ½ heart/sec or grants extra hearts if full, then triggers a 3‑minute cooldown when you stop). The cleaver also emits whispers, shows red “blood” particles on hits and during Revenge, forces a red “blood moon” night while at 20 charges, and displays a one‑time in‑game help sheet the first time it’s in your inventory explaining all abilities and controls.

**Soul Reaper Lantern** A legendary scythe that hungers for souls and grows more powerful with every kill. This mythic weapon automatically harvests souls from slain enemies—regular mobs grant 1 soul while players grant 3, up to a maximum of 100 souls. Each collected soul increases your damage by 0.5, allowing the weapon to become devastatingly powerful as you reap more victims. When you strike an enemy, the Soul Reaper Lantern unleashes its signature Reaper's Reach ability, creating a sweeping 3-block arc that damages and ignites all nearby foes, while the primary target burns from the Flame of Torment for 5 seconds. With a 25% critical strike chance, high base damage of 110, and soul-powered scaling that can add up to 50 additional damage at maximum souls, this cursed blade transforms you into an unstoppable force on the battlefield—just keep swinging to harvest souls and watch your power grow.

Cursed Thread lets you permanently soul-bind one piece of armor to yourself — bind by holding the armor in your off-hand and right‑clicking with the Thread in your main hand — the bond is irreversible and the armor grows in protective power the more you wear it. The bound armor gains an enchanted glint and special tooltip, slowly drains hunger and very slowly loses durability while worn, and will never drop on death: the Thread quietly removes it from the death drops and restores it to the correct armor slot or your inventory on respawn (if keepInventory is enabled the item simply behaves as normal without duplication); only one piece can be bound at a time.

This mod adds the Creeper Echo Cat, a matte-black nocturnal cat with a glowing jack-o'-lantern face that appears once per Overworld night near a random non-creative/spectator player, silently sneaks up on the surface, freezes briefly if you look at it, plays a creeper-priming sound when close, then flees and despawns — if you hit it it drops rare (90%) or epic (10%) loot before disappearing. When it “primes” the encounter is dramatized with layered cave and heartbeat sounds, expanding rings and clouds of smoke, soul-fire, end-rod and portal particles, and it briefly blinds, slows, and nauseates the target; if seen before the scare it glows with an Enderman scream, and it vanishes with a dramatic teleport/puff effect while being hit triggers a totem-and-wither-like explosive particle-and-sound burst.

Pumpkannon — The Lantern of Madness is a sentient lantern‑cannon with four unlockable in‑hand combat abilities you use directly: Confetti Burst (right‑click to fire), Spectral Beam (press R), Void Parade (press V) and the Grand Finale (press G); each ability’s tier and cooldown are shown as pill‑orbs on the in‑hand HUD. Upgrade and permanently buff it at a Lantern Altar by placing the Pumpkannon, adding offerings and pressing LIGHT THE WICK (shift‑click will auto‑prioritize): Honey Bottle ×3 converts to one Honey tribute (+5% projectile speed per tribute, stacks and now correctly affects all four abilities) and Pumpkin Pie ×5 converts to one Pumpkin Pie tribute (+0.5 Max HP per tribute while held, stacks; the −25% cooldown reduction applies only once on your first pie tribute). The Pumpkannon tooltip shows live counters and buff lines (e.g. “Honey Power” and “Pumpkin Power”), F3+H reveals a compact stats section, all counters/buffs are server‑authoritative and sync instantly, and the Max HP bonus is applied while holding the Pumpkannon (health is clamped safely if it exceeds the new max).

The Dreadflight Witch is a terrifying flying hostile mob that haunts the skies as a larger, more menacing witch who hovers on a visible broom, cackling as she stalks players, swooping down for brutal melee strikes and periodically sending out small swarms of bats for ranged magical attacks. Her broom now sits noticeably higher beneath her as she patrols, and while flying she emits subtle soul-fire flame wisps around her midsection and occasional sinister sparkle particles near her face for an even more ominous presence.

**Totem of Sculk** This mystical totem harnesses the ancient power of the Deep Dark to protect you from Wardens. Simply hold the Totem of Sculk in your main hand or offhand to make all nearby Wardens completely passive toward you—they will no longer target or attack you. Additionally, right-click while holding the totem to summon a weakened Warden with reduced health (25 hearts instead of 250), which can be used strategically for combat or collection purposes. The summoning ability has a 5-minute cooldown, and you'll receive feedback messages indicating when the totem is ready to use again.

The Lost Darkness – Endless Nightmare adds the Frenzied Relic, a black-and-red pulsating idol you right‑click to trigger an endless, escalating nightmare sequence. Once activated (10‑second cooldown), the relic layers darkness, vision flickers, nausea, phantom attacks, Warden ambushes, teleporting/jump scares, inventory “cursed” items, lightning, falling blocks, TNT/lava rain and other environmental chaos with periodic taunting messages and a rare cursed chest event — the cascade keeps overlapping and intensifying until you die or disconnect. The effect is per-player and contained to the game (but will alter terrain), so try it in a copy of your world; right‑click again after cooldown to re-trigger and use any cursed items that appear for extra scares.

This mod adds the 'Chalice of Bloodfeast' item into your world, the item cannot be crafted and instead can only be found in a very rare structure called The Cathedral, which can be found rarely in any plains biome on the surface, or much more commonly in a pale garden. Upon consuming the chalice, you'll immediately notice the hunger effect, and a new bar on the right hand side of the screen, the way you play in the world now revolves around this bar, as it's your only way of remaining fed and healthy. Below a value of 5, you'll gain constant hunger. The bar decays by 5 every 5 seconds to heal you if you are missing health, and it decays by 3 every 6 seconds to feed you if you are missing food. Above a value of 60, it passively decays by 1 every 3 seconds. Above 40 value, you'll notice a passive speed buff. Above 60, you'll notice an aura around your character, causing you to deal and take an extra point of damage naturally. And above 75, you'll gain slight lifesteal on hit. There are some more things to go over, but those can be experienced in game, much like the abilities. As this is just a teaser of another mod I'm making, I've automatically included the 4 abilities you'll have. These cost bloodfeast to use, naturally. The 'Single' ability can be used up to 3 times during its windup to increase its damage. The 'AoE' ability grows stronger the more entities it hits. Do note that being around or in water/rain will weaken and slow you. And eating any normal food will poison and give you hunger. There is also a mechanic to create a chalice using bloodfeast by shift rightclick while holding a glass bottle. Do note that this is supposed to make it so people who drink that one have a max bloodfeast value of 90, and it decreases as it goes on. (untested unfortunately). There is also a keybind to make a chalice, however this is a failsafe in the event shift rightclicking does not work. please note: each player can only ever make 2 chalice's. Inspired heavily by project moon Released early for the halloween 2025 modjam

A mystical wand inspired by the wizarding world of Harry Potter. Shift and punch to reveal a spellcasting menu containing 30 different magical spells, including Wingardium Leviosa and many more enchantments. Channel your inner wizard and cast spells throughout the Minecraft realm.

This mystical tome harnesses the dark powers of Halloween night, offering five distinct supernatural abilities that can be cycled through by shift-right-clicking. Right-click to activate the current mode: Haunted Light summons ghostly particles and grants glowing, Soul Harvest provides strength and absorption while healing you when striking enemies, Fog Vision creates an eerie orange mist and grants night vision, Spectral Ward offers powerful resistance and fire protection, and Night Caller plunges the world into darkness surrounded by soul fire flames. Each mode unleashes unique particle effects and magical enhancements, making this tome a versatile tool for wielding shadow magic.

The Necromancer is a powerful boss — an oversized zombie with 315 health, a visible set of iron armor, and a purple boss health bar; he never despawns, doesn’t burn in daylight, can’t pick up items, and his armor and weapon won’t drop. On spawn he utters ominous lines; at 150 HP he summons three skeletons and two baby zombies (the babies gain Poison II), and at 100 HP he draws a diamond sword, gains Speed I and blinds a player for 20 seconds. He no longer appears naturally and must be summoned using a mid-game craftable spawn egg.

The Death Sigil is a mystical relic that surrounds the wielder with a deathly aura, causing nearby creatures to wither and decay while it’s held. It can now be equipped in either your main hand or offhand so you can keep the aura active while using a weapon or tool in your primary hand; combat attacks will still be performed with your main hand.

This mod adds the Tarantula Broodmother, a towering boss spider twice the size of normal spiders with 129 hearts and an orange boss bar; it performs a devastating 12-block super jump that crushes nearby players and, when slain, spawns seven hostile baby spiders. Its attacks have a 30% chance to inflict Poison I for 3 seconds plus nausea, and it will no longer appear naturally in the world — you must summon it with its craftable spawn egg.

The Blade of Thanathos is a legendary netherite sword that deals 12 additional damage and automatically sets enemies on fire for 8 seconds, while cursing player opponents with Wither II for 5 seconds. Right-click to throw the blade like a trident—it will automatically return to you after impact. The sword features three powerful abilities activated by keybinds: press V to summon three demonic warriors that fight for you with netherite swords, press B to launch explosive fireballs at your enemies, and press N to unleash a devastating black hole that instantly kills all hostile mobs within 15 blocks while safely protecting you and any players holding Totems of Undying.

This mod adds the Clown Axe Runner, a terrifying hostile mob that takes the form of a creepy clown wielding an iron axe. This nightmare-inducing creature is faster and tougher than regular zombies, with 15 hearts of health and enhanced speed that allows it to chase down players relentlessly. Unlike normal undead mobs, the Clown Axe Runner doesn't burn in daylight and will persistently hunt players within a 40-block range, making it a dangerous threat at any time of day.

The Possession Ghost is a fragile(gets killed in one blow), glowing specter that drifts silently through the night and, upon touching you, vanishes into your body—forcing you to attack peaceful creatures(and you lose all control of your character). Once it locks on to a target you won’t stop until the prey is gone or you wander too far, and when no prey is in sight you roam aimlessly like any wandering mob. A player only gets freed once they die in one way or another(or you clear it with /effect clear).

The Big One is a radiant golden creeper that glitters in sunlight and keeps the classic creeper look with a metallic sheen. If you kill it with a golden sword it will die peacefully with a dramatic explosion effect, drop generous amounts of gunpowder, TNT and sometimes gold blocks, and grant the nearest player the Hero of the Village status for two Minecraft days; if killed any other way it detonates in a massive, destructive blast and drops nothing. Nearby villagers within about 10 blocks will wake and flee in panic when it approaches, and iron golems will ignore it.

A lanky, obsidian-black entity that towers over most creatures of the realm, the Crimson Gaze Enderman stands as a nightmarish evolution of the standard Enderman. Its elongated limbs move with an unsettling grace as it teleports across the landscape. What distinguishes this horrifying variant are its eyes - intense crimson orbs that pulse with a malevolent glow, cutting through darkness like twin beacons of doom. The crimson light occasionally streams from its eyes like bloody tears, leaving a momentary trail as it moves. This formidable entity possesses strength far beyond that of its common brethren, capable of ending a fully armored adventurer's life with just two devastating strikes. The air around it seems to warp and distort, and the ground briefly scorches where it stands. When provoked, the Crimson Gaze Enderman emits a bone-chilling screech that echoes across dimensions, serving as a final warning before it unleashes its terrifying power.

The Corrupted Peekaboo Creeper is a ghostly, glitched creeper with pale skin, mint-ice blue glow artifacts, scanline noise and torn, hollow sockets that glow neon-blue; it hovers in a faint silhouette and, instead of exploding, playfully startles you with a layered "Boo!" and ambient stingers, sometimes hopping and vanishing in a smoky poof to reappear behind you when struck. It’s tougher than a normal creeper and will occasionally flicker invisible for a brief instant with a small poof to hint at its presence. When defeated it emits an eerie Enderman-like death cry and spawns a burst of 20 bats as it drops ectoplasm and spectral dust.

Drink the Blood Hound Brew to begin a 10‑second transformation (blindness and nausea with an on‑screen message); when that ends you enter an 11‑minute empowered phase. During the empowered phase you gain Speed II, Regeneration I, Strength I, +7 absorption hearts and Saturation, but you cannot use items, tools, or weapons —

The Spirit Shulker is a striking white shulker with extra health that fires projectiles more quickly, slips into invisibility between attacks, and teleports short distances while invisible; its projectiles still cause Levitation. When you hit it, it retaliates by briefly inflicting Blindness for 3 seconds and its invisibility resets. It only naturally appears around midnight, though spawn eggs and spawners let you place it at any time.
