This is DeV's Vanilla+ style mineacraft mod pack for his server. It has a bunch of base client side mod for improvement, along with some visual mods to spice up the gameplay. It also has a few simple mods that add things like waystones, and furniture, passive skill treem, and some mob combat changes to the game.
I recommend installing this shader pack: https://modrinth.com/shader/complementary-reimagined
