Through the code, we can use the “gold_wizard” to shoot small fireballs if fire charge is an ammunition having the minecraft:projectile component mentioned in offical documentation.

![Note] Ammunition used by minecraft:shooter must have the minecraft:projectile component in order to function properly.

Of course fire charge has the component, else it won’t be able to be shot from the dispenser.

In addition, arrows and snowballs are valid ammunitions. The snowballs are throwable while arrows are not. The snowball and the arrow have same identifier with their projectile entity while fire charge is not.

In conclusion, there’re 3 possible cases:

• The documentation is incorrect.

• The fire charge hasn’t minecraft:projectile component. (but how?)

• The wizard needs more settings.

They didn’t show me an error log. So I suppose I don’t need more settings.
