The Angry Ghast

After the Vanilla (sad) Ghast and the Happy Ghast... wasn't something missing?

Introducing: The Angry Ghast – a mod that adds three new Ghast-themed bosses, one for each dimension

How do you spawn one of the three bosses?

The first step is finding a Burnt Ghast in a cave:

(Or you can craft one if you don't have time)

Next, you'll need to heal it by surrounding it with Snow in a Crafting Table

Now, all you need to do is place the Healed Ghast on the ground, and the boss of the corresponding dimension will be summoned after a few seconds!
(It's recommended – though not required – to follow this order: Overworld, Nether, End)

Have fun with three new bosses, unlock ten new advancements, and collect twelve unique items and weapons!
