Mega Ghast

Mega Ghast is a Ghast boss mob that is 2 blocks taller than a regular Ghast, and have a crown on their head. They spawn in unique tower structures that are rarely found in the Nether. It can be found on the highest point on the tower: floor 10. The other 9 floors have some other Nether mob rooms. Mega Ghast can’t go through walls, but can shoot 3 fire balls at once and go completely invisible for 10 seconds. Once killed, you’ll get its crown, which will let you shoot fireballs. Also, did I mention you can put it in an anvil to combine it with any helmet you want? Well, yes you can! Add this into 1.21 to give some players a good challenge, since this update is all about challenges.
