soul sword

the sword needs to be made of one diamond sword surrounded by 8 soul sand. It can not be turned into a netherite sword and a netherite sword cant be turned into a soul sword. This sword when you hold it will add a need bar called the soul bar. the bar starts out at 0 souls and has a max of 10 souls. for each mob, you kill you get one soul. the number of souls you have changes the damage you deal. 0-2 souls make you do as much damage as a wooden sword. 3-to 5 souls make you deal as much damage as a stone sword. 6-7 will make you do as much damage as an iron sword. 8 souls do as much as a diamond sword. 9 souls as much as a netherite sword. and 10 full souls will do as much damage as a netherite sword with sharpness 5 but once hit with 10 souls, the souls would be released and then you'd go back to having 0 souls. and every minute it would lose 1 soul. it has as much durability to an diamond sword.
