witness my stand(stands name)

you bring forth a manifestation of your will.the appearance is chosen by you(nothing too crazy)the stand can be seen by people who can also use the spell.if the stand is damaged the caster takes the damage as well. the stand can preform basic tasks and when its not be commanded it is dispelled. the stand is commanded telepathically instantaneously.in combat roll1d6(+your highest attacking proficiency)  to attack with your stand. your stand will unleash a flery of punches at the enemy. at level 1 your range is 30 feet and roll 1d6, level 5 your range increase by 15 and you roll 2d6, level 11 your range increases again by 15 you roll 3d6 and can choose to attack with your stand but u lose any bonus action that turn,at level 20 you roll 3d10 and can attack with stand without penalty. (dm may nerf/buff your stand for story development/ or if they feel like its too powerful)(consult dm if you are planing  to be a stand user specially if you are planing to have it use abilities) each stand is different based on class so be imaginative ;)
