Hey guys, I play against a good buddy of mine who rocks the Decurion Detachment for his Necrons and my head has been swimming in the special rules throw around by it. My question is this... do Tomb Blades have access to a 3+ invulnerable save via formation/warlord trait/other shenanigans of some kind? I've been hunting around to see how this is possible and I haven't seen it.... I know they can upgrade to standard 3+ armor (not invlun) but haven't seen the Invuln upgrade....if you guys let me know I'd really appreciate it. Thanks so much!
