I was looking around in KbrickGold's island, then I noticed there is a wither inside the cathedral, I thought it wasn't possible to summon a wither.
Withers can be crafted, but it's a bit wasteful to do so, since they require three wither skeleton heads and only drop soul sand when you kill them.
obviously in on the ground but it would be cool to make a wither pop up after you craft one in a crafting table
I guess I was mistaken. I don't think so. They cannot damage terrain. They will still try to kill any nearby players or mobs, though. Hopefully the rarity and value of the wither skeleton heads needed to make them with will keep them from becoming an issue, otherwise we'll have to prevent them from spawning.
I've summoned a wither once, I do not recommend it. People will try to kill it, and there's nothing you can do. Even if they are hidden, players with hacks can glitch into it and kill it. They do not damage blocks, but they do damage you (unless you have /god). You can name them.
That was fungamer333 's fault! But it was worth it, I got my 3 heads back! I think it was always this way, but it took long until I first tried it.
