Wither God
The mod «Wither God» introduces a new boss to Minecraft Pocket Edition, specifically a modified version of the familiar Wither! This mod is perfect for players who have advanced in MCPE to the point where they consider themselves gods of the game! This boss is significantly more dangerous than the regular Wither, especially in the area surrounding you, as Wither God will obliterate everything in its path, and even creative mode won’t save you from its pursuit! The only way to distract it is by spawning another mob in Minecraft Pocket Edition…
Let’s see who the real god is 
How does it work?
In terms of summoning the new boss, you won’t find anything new; as per the standard in MCPE, you need to use 4 soul sand blocks and 3 wither skeleton skulls. The only difference here is, of course, the threat posed by the new boss in Minecraft PE!
Another distinction between the regular Wither from Minecraft and the new Wither God is that the new boss will destroy everything in its path! Even creative mode, where you might hope to hide, won’t protect you!
Let’s conduct a small test in a regular MCPE world. The Wither God was spawned, and just look at what happened to the world in only 3 minutes… A large portion of the area was completely devastated.
I strongly advise against using the Wither God mod and summoning the new boss in important worlds, as your constructions will be utterly destroyed..
