Awakened Technique: Planet Slicing Cut

By expanding the target of your Dismantle to the world, you can perform a slash that cuts through space itself. On your turn, as an action, you may begin chanting. While chanting, you may not do anything except continue to chant as an action or cancel the chanting as an action. If you stop chanting for any reason, you do not get the Sorcery Points back, and you must restart chanting from the beginning if you activate this Technique again. After 3 actions spent chanting, immediately activate Dismantle as a bonus action to cut through an area of space in a line starting from one point you can see within 30 feet of you extending for up to 40 feet to another point you can see within 30 feet of you, dealing 6d12 slashing damage to every creature caught inside. This damage bypasses resistances and immunities. This Technique cannot trigger Black Flash.
*"Hide of the Reptile. Double Asteroids. Knock Back." The first phrase is said when you start chanting, the second phrase on your second turn, and the third just before you unleash the Technique.
