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.
