Notice: This mod will (probably) not recieve a further update. This being a Minecraft mod really restricts what I can do.
Minecraft Forums thread: https://www.minecraftforum.net/forums/mapping-and-modding-java-edition/minecraft-mods/wip-mods/2992858-essences-mod-explore-and-craft-some-powerful-armor
The core of the mod is the Essences. The Essences are really powerful stuff, and you can use that to craft some powerful tools, weapons and armors. Better than Diamond! There are 3 Essences (Electric Essence, Nether Essence, Ender Essence). You craft Essences using drops from themed mobs. You'll need a lot of stuff to make Essences. Detailed description of the mod is in the Minecraft Forums thread (it's an update out of date, but most information, except the stats, still apply).
Feel free to use the mod in any modpacks. You are allowed to use it, and you do not need to ask for permission.
fix the bull in hell, or it even kills in the creative
In reply to bloger_1:
That is an intended feature. In fact, every mob can kill you in creative mode. To prevent dying in creative mode, wear full ender armor and enter this command: /effect @s 6 100000 10. You probably won't die with that, but I don't know for sure since the bosses can do 500+ damage in a single hit. And don't think infinity armor will work against them, or the infinity sword can kill them in one hit. I might add a creative-only armor though...
