ARTHROPOD PHOBIA EXPANSIONS

ArPhEx - THE ULTIMATE ARTHROPOD PHOBIA HORROR MOD WITH POWERFUL BOSSES + STALKERS + REALISTIC INSECTS, ARACHNIDS, CENTIPEDES, CHELICERATES, AND NON-ARTHROPOD WORMS - GECKOLIB REQUIRED

Feel free to use this mod in any modpacks. Highly configurable, the spider moth dweller can be disabled entirely if preferred, or adjusted in health/spawnrate - For further configuration options, I recommend the compatible "In Control" mod. (credit to srfoloso for suggestion). All mob spawns are uncommon, optimised as much as possible for a surprisingly lightweight/unobtrusive mod. Suggestions very welcome - you can contact me at v4ll4x@gmail.com , on discord (username vllaxa), or in the Curseforge comments.

SPIDER MOTH

Multiple phobias combine to create a nightmarish creature with high mobility, similar to Mothman folklore.

Beware the thunderstorms

[BOSS]

A truly overwhelming and ominous force of nature - Survival will not be easy, this entity is death incarnate. I have created a new "dweller"-style mod with extensive detail, including many advanced mechanics:

Fully custom entity with intricate custom model, textures, particles, animations, and terrifying sounds Progressive terraria-like system where the naturally spawned dweller will be weaker and disappear after a few hits until the player "wards it off" three times. From then on, it will spawn at full power for that player. If a player kills it twice at full power, it will stop spawning naturally near that player (but can still be summoned with the structure). Adaptive wing buzzing sounds that modulate based on movement speed. Multiple jumpscares/hallucinations Intelligent stalking and reaction to being looked at - it can track you across long distances (long render distance recommended). Spawns additional versions near to the player that follow closely or run away (despawning if not in darkness), stalk continuously with brief appearances, or fly around in the airspace near the player Ability to walk/run, fly anywhere, break out of blocks, and turn into smoke to pass through 1x1 spaces Ability to break doors, non-stained glass panes, and leaves, or drop torches to the ground on close contact. Mob griefing rules control these mechanics Flies over water, rather than getting stuck. Crash effect when landing from a height Multi-phase boss fight mechanics with second stage at half health (bloody texture + extra invisibility ability) - emits less and less particles as its health decreases. Variable hitbox size Lifesteal and damage blocking abilities Ability to grab onto entities and hold them in place, or throw them Can also spawn on cave walls or on large trees in a sleeping mode, easily woken up if approached without sneaking Summoning structure Eerie clones appear nearby to distract the player, with a chance to float into the sky. Variable sizes including enormous giants can spawn The dweller can summon multiple types of minions, including ghosts that fly through walls and teleport it to you if you let them hit you (when the dweller can't reach you otherwise). These teleporter ghosts also spawn naturally in crimson forests, and die if a block of mangled spider flesh is nearby. All attack phases are contained within a single dweller entity, rather than spawning multiple versions Epic items as rewards for killing the dweller boss, plus advancements The main spider moth entity can spawn during thunderstorms (configurable). It rarely spawns, and can spawn either on the surface or underground. Since the dweller spawns rarely (low rate, only in thunderstorms, and only in select vanilla biomes, it shouldn't become obtrusive or annoying like many other dwellers - this can be changed in the config file.

Biomes the spider moth can spawn in: Plains, Desert, Dripstone Caves, Lush Caves, End Barrens, Sunflower Plains, Snowy Plains, Meadow, Soul Sand Valley, Snowy Taiga, Jungle, Crimson Forest, Grove, Savannah

Planned additions: Additional even more powerful boss version with spider moth pet as the reward for defeating, further sound improvements, an additional spindly stalking variant that follows you with multiple entities at once, another flying mode for the main dweller where it circles you like an enderdragon during the bossfight, and general further optimisations to every existing mechanic. Also planning to add one or two more "dweller"-style stalking entities, like a demonic flying stalker in the nether.

ARTHROPOD EXPANSIONS

This mod features a wide range of high-detail, realistic arthropod and worm mobs, focusing on those likely to induce phobias.

Planned: Mosquitos, flies (including crane flies), locust swarms, more moths, tameable butterflies, and even a tameable spider moth dweller variant. Two more bosses planned. Also planning countless improvements to existing entities, but not in a way that will make the mod become bloated. Planning to add a custom arthropod-infested biome with dungeons in it, or at least a large dungeon. Open to suggestions.

CURRENT:

Most added mobs can climb walls. Some of them can spawn in large groups.

Centipede Evictor [MINIBOSS] - Huge house/cave centipede boss with an intricate model and realistic animations. This large and extremely powerful boss entity can spawn larvae, and it can also spawn tiny centipedes that crawl through the walls to attack you. Therefore, it is called ‘Evictor’ because it will forcibly evict you from your home, just like a real house centipede might! It can see you through walls in order to do these attacks. Beware its extreme speed and strength - It will be necessary to use the environment to survive as it has a large hitbox. Drops a quarter of an Abyssal Crystal, providing an alternative way of obtaining it if you disable the main Dweller boss.

Widow spiders [MINIBOSS] - Huge black widow spiders that spawn rarely in dark forests and deep dark biomes. They are strong, and have both melee and ranged attacks. Their ranged web attack is cumulative, giving the target a "webbed" effect that stacks up to level 5 if hit again before it expires. While the player is webbed, the spider keeps its distance (and is immune to arrows). Additionally, it drops spinnerets, used to craft a web sling grappling hook that can upgrade further to a "tarantula tether".

Small spider larvae (house spider) entities can spawn in packs or be summoned by clones of the main dweller. They can jump and literally grab onto the player's head, inflicting continuous damage, or hang from the ceiling with realistic webs in wait of an unsuspecting victim. (colour and size variations)

Spider flat (giant huntsman) - Tameable! Large, fast spiders modelled after giant huntsman. Dangerous, strong, and highly creepy, but tameable with maggot or roach grubs (don't feed them the wrong food or they will be angry). When tamed, they follow and teleport like wolves, plus can be stored in a Spider Jar item. Fully renameable with nametags or anvil on the jar.

Funnel (web) spider mob can spawn rarely near spider larvae. They surprise the player by leaping from their hidden funnel web burrows when near - when killed, they drop a venomous fang. Large and highly dangerous, giving a necrosis effect on hit that works like the opposite of resistance.

Goliath spiders (tarantulas) are the strongest non-boss spider-type. Four different variants. Variant 1 is a large goliath birdeater with strength and resistance (plus special ability to urticate, throwing hairs that cause blindness/slowness), variant 2 is another creepy brown tarantula that is immune to drowning, variant 3 is a dark, fast tarantula, and variant 4 is a Mexican red-kneed tarantula with immunity to fire. All tameable with buckets of maggots/roaches! Tamed versions are rideable and fight for you. When riding, you can climb walls or jump by pressing ctrl/cmd.

Brood spiders (wolf spiders) are large and drop off tiny spiders when attacked or killed. They have venomous melee attacks and ranged web attacks

Lurker (sea) spiders - Large spindly water-based spider creatures that spawn near tropical fish, walking on the ocean floor. Not even the oceans are spider-free.

Centipede Evictor larvae - Extra-realistic centipede designs/animations. These small, rapid enemies spawn rarely in various biomes such as swamps and lush caves. On spawning, they have a one in five chance to be a darker cave centipede (instead of a house centipede), with black particles coming out. If you kill one of these while in a wide open space, that is how you spawn the main Centipede Evictor miniboss.

Centipede Stalker - Maximally creepy giant centipedes can spawn in various biomes, above and below ground. Fully animated with 20 body segments and 19 pairs of legs, along with stalking mechanics (around walls) and ability to hang off the ceiling until you get close.

Hornet Harbinger - Realistic hornet/wasp mobs that spawn in packs to hunt you down and sting you with necrosis and withering effects. Additional giant variant is larger and stronger, dropping a venomous fang on death. They attack bees.

Smaller, regular spider moth larvae enemies with ranged and charge attacks can spawn from the main spider moth (whenever it kills any entity, or occasionally during the fight) - Their ranged attacks can heal the spider moth, so it is crucial to eliminate them.

Silverfish spectres are realistic versions of the silverfish mob, with an extra ability to go invisible periodically. (size variations)

Spindly longlegs harvestmen/cellar spider arthropods rarely spawn, mostly underground in large packs. They are neutral mobs, becoming aggressive if attacked. (colour and size variations)

Menacing scorpion/sun-spider hybrids can spawn in various hot biomes like deserts. They have a chance to grab onto the player with their pincer upon landing a successful hit, along with having paralysing venom. (colour and size variations)

Maggots/grubs that spawn rarely in packs of up to 40, each with random sizes. They poison the player on contact, and can be consumed as food or crafted into a bucket of maggots (8 grubs+bucket). (colour and size variations)

Cockroaches/water-bugs can spawn in various biomes, and can be consumed as food or crafted into a bucket of roaches (8 grubs+bucket). (colour and size variations)

Rhino beetles can spawn in caves and jungles. Their phobia element comes from an ability to randomly start flying with wings sticking out and a noisy buzzing sound.

Small ticks/beetles/mites can spawn similarly to cockroaches, adding additional variety with different spawn textures (colour and size variations).

Giant ants spawn in groups, following each other over long ranges and fighting off attackers. (size variations)

Creepy bloodworms spawn rarely in groups, each with random sizes and detailed realistic animations. (transparency and size variations)

GENERAL MOD DETAILS

When the spider moth is stalking you, it will give you a terror effect (mining fatigue + occasional shaking):

The spider moth is powerful enough to kill wardens, withers, and strong mod bosses, yet fully possible to defeat with vanilla (ideally ranged) weapons and craftable items that slow it down. Any naturally spawned dweller will stalk you down, keeping at a distance until you look at them or walk too close. Once triggered, it will run or fly at you aggressively, breaking any leaves, doors, or window panes in its way, or sending out teleportation ghost minions if it gets stuck. If you don't have the powerful tools necessary to kill the spider moth, you can get rid of it by dying, escaping to another dimension, or running far enough away that it despawns. If it has full health, spawned naturally, and has not yet been killed in its full form, it will have a chance to despawn each time it touches the player.

A craftable item that slows it down and prevents its lifesteal is called Bane of the Darkness, in addition to providing immunity to darkness effects. Another item, Mantle of Vitality, provides immunity to wither, necrosis, and poison effects (crafting requires a lodestone and enchanted golden apple).

Other craftable items include the Web Slinger, Tarantula Tether, Dagger of Dissolution, and Abyssal tools.

The web slinger is a grappling hook crafted from spinnerets dropped by black widow minibosses. You can pull to walls and hang from them, or pull entities towards you. You can upgrade it to a more powerful tarantula tether, with double the range and power. The dagger of dissolution crafts from venomous fangs dropped by funnel web spiders and giant hornets (both very dangerous mobs). Like those mobs, it gives a necrosis effect on hit, acting like the opposite of resistance by amplifying damage taken to the affected entity and making them temporarily more vulnerable to all attacks.

Necrosis damage mutiplier: damage amount * ( (effect level + 3) / 2.5 )

Killing the spider moth boss will give you an abyssal crystal that provides strength when held. This crystal can craft with other items to produce legendary abyssal tools that glow to warn when you are being targeted for attack.

The abyssal blade is an unbreakable weapon capable of acting as a powerful sword, shield, ranged weapon, mobility item, and general protection item. It has further abilities, like weakening, slowing, and withering enemies, plus providing immunity to withering, necrosis, and darkness effects when held. You can wield two at once, or wield it with an abyssal crystal or dagger offhand for additional powerful abilities. The abyssal pickaxe is an unbreakable tool that can mine two blocks at a time by providing an extremely high haste effect immediately after breaking the first block. Right click with the Abyssal Blade in your offhand while this pickaxe is in your main hand for the option to temporarily switch from a fortune enchantment to silk touch, plus temporary night vision if you have a Bane of the Darkness in your inventory. The abyssal dagger crafts from the dagger of dissolution, serving as an upgraded unbreakable version of that item dealing a higher necrosis level on hit. It glows when targeted like the other abyssal tools, and provides invisibility when attacked along with slowing the attacker.  Craftable thunder sensor item glows when a thunderstorm is happening, letting you know that the Spider Moth could spawn at any time.

Summoning structure also available for the Spider Moth Dweller - You need a Bane of the Darkness in your inventory. Then, simply place a block of soul sand atop a block of fermented spider eyes, and light it on fire:

Enjoy!
