Spooky Jams
🫙 SpookyJam 2025: Adds various craftable "Spooky Jams", which give effects when consumed.
About this Mod
Spooky Jams is my 2025 entry for SpookyJam, an annual Minecraft mod jam. While the naming is deliberately intended as a pun, it adds actual "spooky" jams which when consumed give the player various potion effects. It also adds the Spooky Yam crop. Which can be turned into a Spooky Yam Jam!
All jams can be shapelessly crafted. The base ingredients are a glass jar and sugar. Each jam has two unique ingredients that make up its colour and effects. See the list below for the complete list of jams and their ingredients.
All available config options:

jamConsumeEffectsModifier default 1.0, min 0.0, max 1000.0

To get started craft some glass jars!
