True Caelum only fires when ordered to do so and if the mage isn't capable of doing it then Caelum becomes a useless tool especially when used alone. Caelum is only useful when used in conjunction with something else. If Aries never distracted Leo then Caelum attack would have never connected same with Lucy(gemini) distracting Taurus with her body. The 3rd time used was against Lucy who could barely move. Caelum effectiveness depends upon the state of its target and if its target is aware of the thing then that attack becomes useless but this just comes with being able to summon 2 spirits. One attacks head on while the other one sneeks attack.
