ahsoka destroy lightsaber

The creature stepped toward her, close enough for her to touch. His spinning lightsaber held off attacks from the sides, but was vulnerable from the front. Just as she'd reached for her first crystal all those years ago, Ahsoka stretched out a hand.
Sensing her intent at the last moment, the Inquisitor tried to disconnect his weapon and fight her with two blades instead of one, but it was spinning too quickly for him to do it. Ahsoka's hand landed almost gently on the cylindrical metal, and the Force was with her. The hilt cracked at her touch.
A sharp whine reached Ahsoka's ears, the dark and light song of the crystals struggling for balance. She realized she needed to jump back even farther. She must have nicked the power connection that channeled the crystals inside his hilt, and now it was overloading. If he didn't deactivate it soon, it was going to explode.
Before she could even consider shouting a warning, the red lightsaber burst into a mess of noise and light. Bright spots pricked at her eyes, and then all was quiet. The creature wasn't going to bother her anymore.
