The Double Shulker Shells datapack from Vanilla Tweaks increases the odds of obtaining shulker shells from shulkers, making it easier to craft shulker boxes in survival gameplay.
🧠 How It Works
In vanilla Minecraft:
Shulkers have a 50% chance to drop 1 shulker shell when killed.
With this datapack:
Shulkers instead have a 100% chance to drop 1 shell.
Looting enchantments still apply, giving a chance to drop extra shells.
This effectively doubles the average number of shells you’ll get per shulker kill, but doesn’t make every kill drop 2 shells.
🔍 Key Difference:
This is not a guaranteed “2 shells per kill” change — it's a probability tweak that doubles the base drop rate, making shulker farming more reliable without being overpowered.
