The conversation between human and AI assistant.
How would you prevent a lightsaber's blade from extending infinitely outward?
Is there anything else that can affect the length of the blade besides the power source?
Yes, the length of the blade can also be affected by the kyber crystal that is used to power the lightsaber. The crystal is what gives the blade its color and also regulates the amount of power that flows into the blade. A Jedi can use the Force to manipulate the kyber crystal and adjust the length of the blade as needed.
