A great Modpack for to play with Friends because you don´t even need a Server. Essential lets you play with your Friends just by inviting them into your World without purchasing a Server.

NaturaSteifen is an adventure fantasy-themed modpack that aims to provide players with a fully immersive and engaging gameplay experience that blends magic, technology, and combat together.

NO MORE BORING STRUCTURES. Structures are added with intricate designs decorated with new blocks, containing puzzles to solve, fascinating lore, and new hostile enemies to fully immerse yourself into the world!

(I recommend playing it with Optifine Shaders)
