Humancraft - Realistic Survival:

The Modpack is vanilla plus, meaning that the experience is similar to vanilla minecraft and the changes added to it aren't insanely different, e.g becoming highly tech oriented.
The differences begin with the progression,

Because of No Tree Punching you will have to begin with collecting flint and sticks to make primitive tools, then you will make a furnace but now because of Lit it Up and Burning Furnaces, smelting items has become more difficult.
When you reach the iron age the game becomes for similar to vanilla, the progression will follow with you having to manage your new stats and defending yourself the buffed mobs.

To compensate for the added difficulty, new technology and tools are accessible to you including guns, items from expanded combat and apotheosis. Alongside a skill tree that allows to you strengthen yourself at an equal rate to the mobs.

The Content:

This modpack was made to test how minecraft would be like with all these extra things to manage. This includes the following;
- Thirst (Thirst was Taken)
- Sanity (Sanity: Descent into Madness)
- Disease (Meds and Herbs)
- Temperature (Cold Sweat)
- Diet (Diet)
- Thin Air (Realistic Oxygen/Lungs)

Then there's other environmental mods like Terralith, Serene Seasons and others.
Mobs are also buffed with Auto Leveling, Harder Spawners and Improved Mobs.

To make your playthrough easier I included Passive Skill Tree, by killing mobs you can increase your skill points and invest it into more armor, damage or other benefits.
