My ability for a sword is killing both the player and the opponent, can someone help?

Basically, I made an ability on the sword where you stab them with the sword, they stick to the sword(using weld) and then you slam them multiple times on the ground. The ability works properly, but for some reason when you actually kill the opponent using the ability, it kills you as well which isnt supposed to happen. Help would be appreciated.
