Basically you can craft a weapon from the dragon egg and some other ingredients. The weapon can give you buffs, and the weapon is a little stronger than netherite. I didn’t know know how to make the weapon unbreakable in mcreator but it is hard to break. It is enchantable, but I just made it for a server. When you right click, you get a set of good potion effects for about 20-ish seconds and then there's a cooldown.
