Don't think they are immune to it. On the Wyvern version 40 AP quest I managed to insta-kill both a normal wyvern with Assassin Shiki NP (300% charge, as I remember) and the boss one with a support Assassin Shiki at 500% NP charge and possibly 2 Shiki death resist debuffs (level 7 and level 10 skills, as I recall). So it's definitely possible, just maybe less likely.
