I designed this little datapack to be a fun add-on for my private server. There's more I want to add, but I wanted to get other's feedback and to see what people think I should add.

That being said... What is Intrinsic Magic? This is a very simple datapack that gives you low-level potion effects based on the item in your off-hand.

Here's the list;
Rabbit Foot - Jump Boost
Eye of Ender - Night Vision
Emerald - Luck
Nether Star - Regeneration
Blaze rod - Strength
Heart of the Sea - Dolphins Grace
Soul Lantern - Speed
Glowstone Dust - Glowing to nearby Mobs
Amethyst Shard - Invisibility
Pufferfish - Poison to mobs you bump into
Fermented Spider Eye - Weakness to nearby mobs
Honeycomb - Honey Trails - (great for tracking)
Slime Balls - slowness
Echo Shards - resistance

You can get a book of all effects using
/function intrinsicmagic:book_of_magic_effects

Let me know of your suggestions! I'd love to grow the datapack into something better and cooler
