Does SEE need a Booster character?

4: If SEE uses I Am All The Sith while SEE Cultist is active, SEE cultist against +100% Max Health, +100% Max Protection and Taunt until the end of battle (this taunt cannot be copied, prevented or dispelled).

Shoot, I meant this to say, "until defeated or until end of battle" since he can still be killed and revived at this point, assuming other Sith allies are still active.
