Originally made as a twist for a manhunt that had to be scrapped. I've added a few effects since then including the Potion of Dirt, and the Potion of Launching.
Made for Minecraft 1.21.1 Should work for most versions, although slight changes might need to be made.
All effects follow the same format:
[ x ]
[ b ]
[ ]
x = ingredient b = glass_bottle
These effects are considered "positive" to the player.
Ingredient: Nether Quartz PotionEffect: Long Fire Resistance
Ingredient: Glistering Melon Slice PotionEffect: Strong Healing
Ingredient: Ghast Tear PotionEffect: Strong Regeneration
Ingredient: Sugar PotionEffect: Strong Swiftness
Ingredient: Blaze Powder PotionEffect: Strong Strength
These effects are considered "negative", but can be helpful.
Ingredient: Dirt Effect: Wither Effect: Regeneration Effect: Blindness
Ingredient: Feather Effect: Levitation Effect: Slow Falling
Ingredient: Spider Eye PotionEffect: Strong Poison
Ingredient: Nether Quartz PotionEffect: Long Fire Resistance
