I had been thinking about how they could do this and make it so it wouldn’t be unreasonable. What I pictured is something like this:
Instead of making it so Zombie dies, her health is reset upon a finishing blow. But to feed the Assajj/Daka loss - a new zeta part of her unique that stacks damage and health boosts to all NS for all damage she takes that resets with her health on a finishing blow. That would give a new use to her being geared up completely, would keep some of the damage and health benefits like before, and also a use for that zeta refund.
