Mod adds a few things that will be useful to you in survival
The mod adds silver which has a very bad effect on monsters
From silver you can create armor and also a sword
Also, with this modification, rubies previously removed from minecraft will be added to the game.
From them you can create a sword, and then improve it to make it stronger
You can also create food from rubies, which, leaving you 1 hp, will empower you
