Description

Requires the library mod Collective.
This mod is part of The Vanilla Experience modpack and Serilum's Spawn Bundle mod.
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.
Configurable: ( how do I configure? )
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'.
