Marsh

Marsh is a wet, swamp-type overworld biome. Two mods add biomes with this name, Biomes O' Plenty and Regions Unexplored, and Fear Nightfall includes both. They share a name and a general look, but differ in climate, colour and ground cover. Both have long hostile spawn lists that mix vanilla monsters with many horror mobs from the pack's mods, so the Marsh is one of the more dangerous wet biomes to cross on foot.

Description

Biomes O' Plenty Marsh

The Biomes O' Plenty Marsh has a temperature of 0.65 and a downfall of 0.7, and it rains. Its water is tinted #3f76e4, its fog #c0d8ff and its sky #79a6ff. Standing water is common. Lakes are placed up to ten times per chunk, and the ground around them is covered with tall grass patches, reeds and watergrass. The biome plays the vanilla swamp music and the cave ambient sound.

Regions Unexplored Marsh

The Regions Unexplored Marsh has a temperature and downfall of 1.0, and it rains. Its grass is tinted #7dbf61, its foliage #80c16c, its water #477bb7 and its sky #77a8ff. Its fog is the same #c0d8ff as the Biomes O' Plenty version. Its surface uses mud in patches where a surface noise value is zero or higher, so mud covers roughly half of the ground (inferred from the noise threshold). The surface placement skips any ground that is already mud.

Grass islands rise out of the standing water at sea level (y = 62). Each island is a blob of grass blocks over dirt. Some carry short grass or tall grass on top, and lily pads or duckweed are cleared from their surface. Water beneath them is partly replaced with dirt columns or open water. Dead shrubs grow on dry land, and dead bushes and pumpkins form small patches.

Generation

The Regions Unexplored Marsh replaces the vanilla Swamp biome with a default weight of 50. The Biomes O' Plenty Marsh is registered by its own mod. Fear Nightfall's custom biome table places both by climate. Each shares its climate cell with other biomes of the same type, so Marsh sits next to other swamp and wetland biomes such as the Bayou.

Marsh covers a small share of the land. The infobox shows the share of each variant. Neither variant has any cave share at y = -30.

The pack's horror weighting does not list the Marsh among its 6× biomes, so it is weighted like an ordinary swamp. Its structure list is not reduced, however. The horror structures in the pack are placed about 30% closer together, and several of them can generate here (see the Mobs and structures section).

Features

The Biomes O' Plenty Marsh has these placed features:

• lake water placements, tall grass patches, reed patches and watergrass patches;
• wild carrots, wild onions and wild rice from Farmer's Delight;
• willow trees, swamp flowers, flowering lily pads and selenite geodes from Hexerei;
• wild flax and cave urns from Supplementaries.

The Regions Unexplored Marsh adds its own grass islands, dead shrubs and a small tree group, which is placed in one of ten attempts per chunk on land where the water is not deep. It also has the same Hexerei willows, flowers and selenite geodes, the Farmer's Delight wild rice, and dead bush and pumpkin patches from vanilla.

Both variants also share the ore features of the vanilla overworld, plus Born in Chaos infected diamond ore and black argillite.

Mobs and structures

The hostile list in both variants is long. It includes vanilla monsters such as spiders, skeletons, creepers, slimes, zombies, endermen and witches, with modded monsters added on top. Among the horror mobs, Ghoul and Necromancer are the most frequent. Others include Dread Hound, Nightmare, Bonescaller, Pumpkin Dunce and, rarely, Krampus. The weighted table below lists every monster for each variant.

The water spawns include the Born in Chaos Corpse Fish and Glutton Fish. The Regions Unexplored version adds frogs to its land creatures and axolotls to its water. Both variants have bats, roly-polies, snails and dragonflies as ambient life.

Marsh structures include the Catacombs, graveyard houses, a dark coven from Hexerei, a Born in Chaos infernal pumpkin site and an oak mineshaft from Better Mineshafts. Several of these are horror structures that the pack places closer together.

Tips

• Spiders, skeletons, creepers and slimes have the highest weights in the hostile list, so most encounters in the Marsh are with these. The horror mobs are rarer but more dangerous.
• Corpse Fish and Glutton Fish spawn in the water. Keep an eye on the surface when swimming through lakes.
• The Biomes O' Plenty Marsh carries Tide's swamp fish tag, so Tide Fishing works there as it does in other swamps.
• Mud blocks are a common surface in the Regions Unexplored version. Build on grass or dirt where you can.
