To be honest, the stand should have the ability to “sap” your enemy’s life every time they damaged you or kill For example. King Nothing activates, and if I die by the enemy’s hand or their stand. They/Their stands would begin to crumble into Jigsaw puzzles and begin to float to where I fall/died beginning to reform my body/my damaged stand. Note this would NOT bring me from the dead. It would just save me from the BRINK OF DEATH. If my brain or my soul were damaged beyond repair or resolve to come back…I stay dead Other weaknesses includes, the stand’s method of attack NEEDS you to get hurt/die for a brief moment. If the enemy manages to destroy your body BEYOND repair or BEYOND your resolve…you stay dead
