The quest requires you to kill mobs in any way, the fastest way is to push them into the void with a knockback 3 stone sword. This way can be used on every mobs except spiders.
I recommend you to build a "farm" like this ( I built it in Nether while it can be built in any dimension ) :
For normal hostile creatures, they will try to walk to you and stop at the wall, then you can use a knockback 3 sword to push them into the void without taking any damage.
For witches and skeletons, they won't walk too close to you, so you can use a punch 2 bow to shoot the witches and skeletons which you can't touch them by sword.
For friendly creatures, they won't try to walk to you, so you should stand on the spawner with them to push them into the void.
For normal Spiders, the farm should be changed like this :
This can prevent the spiders from climbing the wall.
For cave spiders, the spawner is cheap and level 1 cave spiders have only 6 hearts. You can kill them with only one hit using a bane-of-arthropod 3 stone sword. I recommend you to build a farm like this :
In this way, I finish Violent Ends in one day.
The reward "Shard of the sky" is a god diamond sword.
