You might want to read this before playing. It is kind of challenging.

Survival aspects have been changed. In this mod pack, there are no ways to craft wooden or stone tools. You have to create flint tools to start out. In your first days, flint is the most important material to have. 

If you are familiar with No Tree Punching, you'd know what this is. I suggest you watch this tutorial if you don't know how to play: https://www.youtube.com/watch?v=mExD38QMa30

You build campfires differently but crafting larger sticks with just 2 sticks and placing them down. You have to manually light furnaces each time you use them. Watch out! If anything flammable is near a furnace while it's lit, it will catch fire! 
This part is really important. How do you light furnaces in the early stages of the game without flint and steel? Well, with sparkling flint of course! Find a lime green tall grass called switch grass, craft it with flint and a stick to get sparkling flint. Use this along with spare switch grass in your inventory to light furnaces.

You don't have to worry about hunger.  You eat food to instantly heal. 

First Aid mod is in this. Helmets are easily the most important piece of armor to have on, otherwise you'll get instantly killed. Bandages are less viable in this case. They take long to heal. You can just eat food to instantly regain health.

BEWARE OF CHARGED CREEPERS! Also consider that the undead are more dangerous the deeper you go underground.

No back packs, but you can create and smelt vessels of clay that act as miniature back packs. You can learn how to make these in the video shown earlier.

At the End of the game (literally), you can get dragon scales by destroying the ender dragon. Use these scales on your netherite items to upgrade them. And with the mod Enlightened, there is much more content in the End dimension. To be honest, I don't know much about Enlightened (it's really cool), so you're on your own.

Make sure you equip all the resource packs when you first load in!

Inspired by Better than Wolves mod, Skemech, and Jesus. Thankyou for your time.
