AbyssalCraft

AbyssalCraft is an exploration-based mod created by Shinoow. It is influenced by eldritch magic and draws from the works of H.P. Lovecraft. It adds 4 new dimensions, new mobs, and new materials. It features its own in-game documentation in the form of the Necronomicon.

Versions from 1.8.8 onwards can be integrated with other popular mods like Thaumcraft 4, Thaumcraft 6 and ProjectE via AbyssalCraft Integration.

Dimensions
The 4 dimensions of AbyssalCraft are collectively known as The Abyss and are: The Abyssal Wastelands, the Dreadlands, Omothol and The Dark Realm.

The Abyss dimensions (excluding The Dark Realm) are accessed by Gateway Keys, which place down a portal when used. To exit the Abyss, the player will have to walk through a corresponding portal in the Abyss dimensions.

Compasses and Clocks do not work at all in the Abyss dimensions. The Abyss dimensions also do not have a day-night cycle system.

The Abyssal Wasteland
The Abyssal Wasteland is the first Abyss dimension that the player will encounter. This dimension has a bright green sky and a dark ground. The mobs Death Ghoul, Abyssal Zombie, Zombie, Skeleton, Spectral Dragon and Skeleton Goliath spawn here.

The Abyssal Wastelands spawns abyssal versions of Overworld ores. These ores spawn at the same Y-level as their corresponding Overworld ore.

Pools of Liquid Coralium generate here. The terrain is slightly mountainous plains with dark green grass. The first boss of AbyssalCraft, Asorah, The Fallen can be spawned here.

The Dreadlands
The Dreadlands is the second Abyss dimension. This dimension has a red, Nether-like sky and maroon Dreadlands Grass on the ground. The Dreaded Abyssalnite Golem, Abyssalnite Golem, Dreadling, Dread Spawn and Dreadguard are the mobs that are found in The Dreadlands.

The ores Dreaded Abyssalnite and Dreadlands Abyssalnite are found in this dimension.

The Dreadlands contain different biomes such as the Dreadlands Mountains, Purified Dreadlands and Dreadlands Forest. Dreadlands Trees are commonly seen here. The second boss, Cha'garoth, The Dreadbeast can be spawned here.

Omothol
Omothol is the third Abyss dimension. This dimension has a completely black sky and the ground is filled with dark gray colored Omothol Stone. Remnants, Omothol Ghouls, Omothol Wardens and the Minions of the Gatekeeper are the mobs that populate Omothol.

Ethaxium Ore are found in Omothol.

The terrain here is generated on sky islands, and falling into the bottom void is very easy. The terrain consists of barren mountains and plains that is nearly completely made out of Omothol Stone. The third boss, J'hazar, Gatekeeper of the Abyss can be spawned here.

The Dark Realm
The Dark Realm is the fourth and final Abyss dimension. Unlike the other Abyss dimensions, The Dark Realm is accessed by jumping off the edge of an island in Omothol. Fall damage occurs when a player enters The Dark Realm. The player can exit The Dark Realm by using a Cha'garoth's R'lyehian Gateway Key to make a portal to Omothol.

Shadow Creature, Shadow Monster, Shadow Beast and Lesser Shoggoth populate The Dark Realm. The terrain here is completely made of dark violet colored Darkstone. The optional boss, Sacthoth, Harbinger of Doom is spawned rarely in this dimension.

Biomes
AbyssalCraft introduces various biomes to the Overworld.

Darklands
Darklands is a biome with purple grass and Darklands Oak Trees. Darkstone and Abyssalnite are found under the Darklands. This is the only biome in the overworld where Abyssalnite spawns underground.

There are 4 variants of the Darklands biome: Darklands Plains, Darklands Forest, Darklands Mountains and Darklands Highland. The Darklands Plains have less trees and is flatter, the Darklands Forest have a lot more trees, the Darklands Mountains consists of Darkstone mountains, and the Darklands Highland have elevated terrain and less trees. Depths Ghoul and Abyssal Zombie spawns in all variants of the Darklands.

Staying for a prolonged amount of time will inflict temporary blindness on the player; this can be changed in the mod's configuration file.

Coralium Infested Swamp
The Coralium Infested Swamp is a biome with teal grass and many Liquid Coralium pools. Vanilla Minecraft trees are found here, but with turquoise leaves. Liquid Antimatter pools spawn under this biome. Depths Ghoul and Abyssal Zombie spawns in the Coralium Infested Swamp.

Anti-Mobs
When a mob or the player gets killed by Liquid Antimatter, which deals 5 points of damage every half-second upon contact, an anti version of the killed mob is generated. Anti-mobs are stronger than its normal variant, and will explode when touching the normal version of the mob.

Rituals
AbyssalCraft includes a magic system called Rituals.

Rituals require altars to be performed. Altars are player-made structures consisting of 9 pillars with one in the center. 8 types of different materials can be used to create altars. The central pillar of the altar is usually just called the Altar, and the side pillars are usually called Pedestals.

Shift right-click an Altar using a Necronomicon to complete an Altar or to perform a ritual. When performing a ritual, items must be placed on the altar, and a type of energy called Potential Energy is required. Rituals are used for various different tasks.
