So i recently discovered in a game with a friend that space marine librarians have this power called null zone that forces me to reroll invuln saves within 24 inches. How do you guys deal with that? My friend insists that it's not cheesey though i made sure to complain about it as much as possible. If i'm going to run into this power i need to figure out a counter or i don't see myself winning many games. I run a slaanesh/tzeench list and have plenty of models for those units but no nurgle or khorne models. Null zone was horrific enough that i was thinking of suicide deepstriking daemon princes with boon of mutation and breath of chaos to try and take out the librarian. That would be 175 points each with the loadout and is kind of a lot of points to deal with some 25 point upgrade or whatever it is. I haven't used fateweaver before but how would his power work against null zone since you can't reroll a reroll?
