Was trying to get Ghast essence for my Flight module, and what better way than to spam a syringe at a ghast so it doesn't die.
Well, turns out the Syringe can capture the essence of the Fireballs that the Ghasts shoots, which overwrites the Ghast essence you already collected.

Of course could be intended to increase the difficulty of getting RF powered flight? :b

yeah, I just had this happen, spent 2 hours in nether hunting for ghasts and trying to get close enough to hit them with the syringe, got to 90%, then Fireball!!! -_-

Can you spawn a fireball?

Doesn't look like it :P
