The lich blade dimension shifting warpped blade

This blade holds within it thousands of souls that have been trapped by the blade. The blades head soul is a lich that was killed with the blade but also had the blade as her philactory. The lich is a undead satyr with the horns twisting and digging into the jaw of the liches skull. The lich has a secretary that the lich uses to talk to users of the blade. The secretary is a devil that maintains a large level of officalness and acts like James Wesley from daredevil. Anyone who touches the blade first comes in contact with the secreatary named Allihstar. After the blade kills ten people the lich will reveal herself to the user of the blade. As the blade kills people the souls of those people are stolen and placed into the blade the remaining husk of a person animates as a zombie. The blade will then inject the user of the blade with a cursed necrotic energy that builds as people are killed. You add one percent to the cursed energy meter every time a person is killed. At 10% the player can talk to the lich freely can imbue the blade into their body able to form and unform the blade as a bonus action placing the blade in their hand as black smoke gathers in its place. The users main hand becomes slightly black with veins colored black as well. The player feels the urge to kill more. At 25% the players whole arm will be covered in the necrotic energy and form two unlocks in the blade. The player will have a strong desire to kill now and will want to acess whether or not to kill each creature they come across. The lich can now invade the players thoughts and sway them to kill. At 50% the player starts to loose a sense of self and has half their torso also covered in the necrotic coloring along with parts of their legs. The Lich can now force a DC11 wisdom saving throw to anyone not close to the user and if failed the player must become violent and maybe kill the creature. At 75% the players entire body besides the head and feet are covered in necrotic energy The DC of the wisdom saving throw increases to 16. The player becomes extremely violent and unhinged. The user gains the abillity to misty step at will and can cast the darkness spell as a bonus action. At 100% the blade breaks and the lich is freed. The body of the user becoems the host and the user is unable to resist anything the lich wants to do. A wish spell can seperate the lich from the user but cannot kill either.
