About Cave Spider Spawn
From Modrinth🕷️ Adds a chance for cave spiders to spawn naturally underground instead of a spider.
Cave Spider Spawn adds a chance for cave spiders to spawn naturally in place of a normal spider. By default they have a 15% chance to spawn and only below the surface, though this can be changed in the config. Adds a bit more difficulty to the game, due to cave spiders being able to poison players and they're harder to hit.
It's also possible to make cave spiders only spawn below a certain Y level. For example below y=0, which is where deepslate is. This is disabled by default, and can be toggled in the config.
All available config options:
Show Spoiler
chanceSpiderIsCaveSpider default 0.15, min 0, max 1.0
The chance a spider that has spawned is a cave spider.
onlySpawnCaveSpidersBelowSurface default true
When enabled, cave spiders will only spawn below the surface.
onlySpawnCaveSpidersBelowSpecificY default false
When enabled, cave spiders will only spawn below the specific y value set in 'belowSpecificY'.
belowSpecificY default 0, min -1000, max 1000
The specific y value used in 'onlySpawnCaveSpidersBelowSpecificY'.
dimensionsToSpawnIn default ""
Dimensions in which spiders can turn into cave spiders, separated by a comma. Leave empty for every dimension. For example: 'minecraft:overworld,minecraft:the_nether'.
biomesToSpawnIn default ""
Biomes in which spiders can turn into cave spiders, separated by a comma. Biome tags work too, starting with a '#'. Leave empty for every biome. For example: 'minecraft:dripstone_caves,minecraft:lush_caves'.
