The caster spends an action to start channeling this spell. While channeling the caster must use their action to channel the spell until they take an bonus action to end the channeling. While Channeling on each turn they can expend a number of spell slots equal to 2 times their spell casting ability score. The spell gains a number of points equal to half the sum of spells level expended.(example if the caster has an ability score of 18 they can expend 36 spell slot and choses 16 1st 14 2nd 6 3rd you. they would get a total of 31 points.) If the caster drops to zero hit points while channeling the caster must make a con save with a dc 10 + the highest level spell slot expended + the round channeled on a success the point from the last turn are kept and on a failure the caster loses half of the points from the previous turn. Then the spell will go off center on the caster as if the caster had ended it.

Once you end the channeling you unleash a line of 100 feet long and 20 feet wide from the caster. Those in the line of must make a con save throw or take 1d12 + spell points channeled narcotic damage* and if killed becomes a zombie under your control or If the creature is undead they come under your control (if it's cr less then or equal to your proficiency bonus) other nonliving being do no reanimate, or on a success the target takes half damage . The caster then gains a pool of healing equal to half of the damage delt. Barriers similar to wall of force are destroyed by this spell but any creature behind said wall would take half of the damage per instance of the barriers.

The healing pool function similar to lay on hands requiring an action and you to touch the target. The healing lasts for 1 hour and then degrades at a rate of 100hp per hour.
