Wither habitat

[Obsi]

There's a doorway at ground level in the centre of each side (marked with torches up the whole height of the wall for visibility) - no doors, just a 2 block high doorway.

After the wither has destroyed the ground, we may have to look ad adding a bedrock staircase up the side so people can back up/out.... though lower down underground it has only "bars" with a 2 block high gap, so players can walk through into any cave systems around and get out that way.

and if one does exist outside the enclosure, then it was spawned there.

Which will obviously not be allowed, withers will only be allowed to be created within the cage/enclosure - NOWHERE ELSE!

Sounds like players are going to get lot of lovin. Just throw them in to fend for themselves
