Getting Death's Hand - TheUnderTaker11/KitchenSink GitHub Wiki
This page will have info on the Soul Swords, Demonic Sword, and Death Scythe.
First you will want to craft yourself 3 soul sword, all tuned to three different mobs.(The zombie, skeleton, and creeper) You could make one tuned to enderman but that is not needed.
How these work is for each of them you need 50 souls of the type of mob the sword is tuned to. After you get those 50 souls, the sword will do 200 damage to that type of mob.
After you get 50 kills on all 3 of them, you will need to make the Demonic Soul Sword, which is able to absorb all 4 of the soul types.
This sword works the same as the regular soul sword but needs 100 kills. Each mob's 100 kills is independent of each other when it comes to doing the 200 damage, so you could have 1 skeleton kill and 100 zombie kills, and it would do 200 damage to zombies.
Now you will have to fill all 4 soul types up to 100 souls, and then you can use it to craft Death's Scythe.
This Scythe does 200 damage to all vanilla mobs, and just 20 damage to anything else. This scythe is so powerful that when it is created it gets bound to it's owners soul, and the 200 damage will not work for anyone else but the original creator.
Get two of Death's Scythes and you will be able to craft The Hand of Death.
The Hand of Death is one of the most powerful items you will ever have in Minecraft. It has two modes, toggled by shift right clicking.
The first mode is the force-kill mode, and what this does is when you hit a mob it will do upwards of 10k damage, and then if the mob somehow isn't dead, then it will force kill them by setting their health to 0.(Note this makes some bosses from some mods not drop items, so be wary.)
The second mode does what the first mode does, except instead of force killing it sets the mob to 1/2 a heart of health after doing the 10k+ damage. This is useful to make sure everything works like it should when you kill whatever you are fighting.
Crafting 8 Emerald ore around this item will give it looting V.
Just like Death's Scythe, this is bound to whoever creates it, and only works for them.
It should be noted if you hit a player with this, it will do 50 damage, as to not fully break PVP.
