Add-on The Wither Storm Boss is spawned just the same way as the normal wither boss. In this game you will need four soul sands and three wither skulls to spawn it.
It's much larger than the normal wither boss and as a result also much stronger. It's most likely impossible to defeat this boss all by yourself. But if you do, be sure to let us know in the comments how you did it!
Shooting arrows is probably the easiest way to damage it in the beginning as it gives you the necessary range to avoid the explosions.
If you get a direct hit by a wither skull then you'll get a levitation effect and it's a risk you'll get killed next. If a wither skull hits the ground then it will cause a lingering wither effect for 12 seconds.
When your Wither Storm Boss lost around half of his health he will be immune to arrows. I wanted to damage him with my sword but it was quite difficult to find the hitbox.
The most efficient way to defeat it is by using Formidi Bombs (TNTs). Place lots of bombs, ignite them and hope that some of them will damage the boss. The Formidi Bomb has a longer fuse than an ordinary TNT but the explosion is greater.
Eventually it was defeated. It drops one nether star. It's a little bit cheap seeing as we just defeated the biggest boss in Minecraft Pocket Edition. But it's definitely a feat worth boasting of! At least if you defeated it in survival mode which I surely didn't.
