With the Wither Minecraft PE
Boss there is something wrong. Someone put a curse on him, probably did Herobrine. Now, Wither possess a new ability that called "Madness". It turns him into another skin, which all at once seems like a safe and deceptive.
New Wither will become a improved boss, because he will have the opportunity to outwit you. So fight with him will become even harder and more fun. You'll need to show some creativity to defeat this monster.
Ritual summoning is carried out in exactly the same way as before. That is, build two Nether blocks in height and width, and on the extreme blocks we put head Nether Skeletons.
Once the heads are installed, the boss will revive and immediately begin to attack you. You have to pre-consider, for example choose the area and wear the strongest armor and weapons.
Be very careful. This new being will bombard by using new shells, of which you've never seen before. Visually it would seem that the shells will not cause any harm, but it is not. Install Madness Wither Boss Addon
