ADAM - Advanced Definitive Adventure Modpack
ADAM is a modpack containing 114 mods.
It changes every aspect of the game: new animals, vanilla animal variants, new mobs, legendary mobs, structures, biomes, custom worldgen, weapons, armors, origins, classes, quests...
The modpack itself it's pretty heavy, but it runs comfortably even while using shaders. Many of the mods can be configured to the players' taste, so everyone can customize their experience.
Right when loading into a world for the first time you'll have to choose a race and a class, and after spawning, you'll get a manual, which you can use to receive a starter armor, weapons and a small passive ability.
After you're done with your character generation, you can get to exploring the world.
There are many new custom structures you can stumble upon by sea and on land and they each offer custom loot, combined from the mods. This means that in a structure from a mod you can find loot from another mod.
In some of the structures you'll even be able to find the new NPCs, which offer challenges and quests, often with desirable rewards.
One of the suggestions I have for the players is to set a goal and try to reach it, this way until you're done your quest you'll never feel bored.
Plus the pack supports multiplayer, too!!!
