So I was playing against a gold Scared Stiff Squigly with fully upgraded Signature Abilities (so it had the "Can't suffer more than 10% of your MAX HEALtH from a single HIT" ability). I was using my Poltergust. I spun up a Dragon Charge and then fired off my RotD BB3, and after the animation, the enemy Scared Stiff had lost barely any health. Like, maybe 10%. I thought this was weird, so I did it again; same result. My attack successfully applied Curse both times, but the damage was way too low (my fighter's FS was equal or greater than the enemy's, so it wasn't a difference in power). My only thought is that the enemy Scared Stiff's SA intervened to prevent the majority of the damage. But according to that ability, it prevents a single hit from removing more than 10% max health. A RotD blockbuster with a consumed Dragon Charge hits 120 times. It's not a single hit; it's a bunch of little hits. So I feel like the error is that the Rigor Mortis SA is treating that multihit attack as a single HIT. I haven't tried other multihit BB3s against Scared Stiff, as a rarely see her in gold PFs. I'd expect Rigor Mortis to negate a BB like Diamonds Are Forever, which hits once, but unless I'm misunderstanding the ability, moves that hit multiple times should be able to deal up to 10% max health damage on each hit, not for the overall attack.
