I created this mod because I always felt that the wither was intended to be a nether themed boss, and it felt silly to be able to summon it anywhere. The mod prevents a wither from spawning anywhere except in the nether. Attempting to summon the wither anywhere else will give the skulls back, so don't worry about accidentally losing your hard earned wither skulls.
In the future, I would like to add particles and sound effects to unsuccessful wither spawns, and I'd like to allow the wither to be spawned outside of the nether if it has been defeated in the nether at least once.
