There's most likely an instant death immunity accessory or armor when fighting against insta-death using mobs/players. Of course, as with any MMO, you will likely sacrifice precious DPS in exchange for situational resistances/immunities.

Aside from that, most likely other balancing factors like party buffs from support classes like Clerics that give temporary immunity, or auto resurrection within a certain time frame after casting. NWs just don't have the proper skills, levels, and gear to counteract what is likely midgame to endgame content like insta-death and other bs like the passive damage reflect Ainz has.

All speculation though.
