It's just a modpack with some mods that my friends and I used to play with.
There are around 140 mods but it can run on less powerfull computer.
You have mods like Mystical agriculture, Mekanism and Iron's spells 'n spellbooks so you can switch between magic and tech. It also features QoL mods like JEI or a mod that add a map. Finally, there is some perfomance mods like Rubidium and spark.
Hope you like it and most importantly Enjoy !
