Force Crest was a powerful ability requiring the use of a lightsaber and fine motor skills. Force Crest was also known as a 'from activation' ability. It was only usable right after activating the lightsaber. When a lightsaber was activated, it released much energy. Force Crest was used to push the extra energy into a wide arc, similar to a crest, which could cut through the tough hulls of a star cruiser. The user of Force Crest would activate the lightsaber and then slash it in an arc motion.
