This instuctable will show you how to fight the Wither. Please note that this is my first instructable.
Step 1: Summoning the Wither
You will need: 3 Wither skeleton heads 4 Soul sand They are both found in the Nether.
Step 2: Fighting It
My advice is go trigger happy with your bow then at half Heath start stabbing it. And so you know it explodes when spawned.
Step 3: After Killing It
It drops the nether star which is used craft the beacon.
