I noticed that the ninja class also lacks this phrasing. The rogue class doesn't mention it stacking because when it was written there were not any other classes that granted sneak attack. The ninja class is a replacement class for rogue, so it makes sense that the sneak attack section was just cut and paste from rogue. IIRC the hybrid classes were also originally supposed to be replacement classes, meaning you couldn't multiclass slayer and rogue.

However, the hybrid classes have become their own independent classes meaning the whole "parent class" portion of the description is purely informative and no longer carries any weight. As a result by RAW these classes do not stack with each other. But every archetype that grants sneak attack calls out pretty explicitly that it stacks with other sources of sneak attack. In fact the way vivisectionist is worded the intent seems to be that sneak attack from different sources is supposed to stack.

At 1st level, a vivisectionist gains the sneak attack ability as a rogue of the same level. If a character already has sneak attack from another class, the levels from the classes that grant sneak attack stack to determine the effective rogue level for the sneak attack’s extra damage dice.

Unfortunately I believe the FAQ overrides the class feature text here. Is there any other argument for allowing sneak attack stacking? Am I wrong and does that text override the FAQ?

Are you talking about the variant multiclassing rules or just taking levels in different classes?

I don't know the VMC rules so if that's what you're asking about I don't know. Otherwise, multiple abilities of the same name stack if the ability in question says they stack. Sneak attack, animal companions and familiars are all abilities which explicitly stack with themselves.

This is regardling normal multiclassing.

All Sneak Attack stack with itself? As far as I can tell only certain classes sneak attack stacks per the FAQ https://paizo.com/paizo/faq/v5748nruor1fm#v5748eaic9o80

Arcane Trickster, Assassin, stacks, Rogue multiclassing with slayer would not stack in this example.

Hello everyone,

I am having a discussion from someone regarding sneak attack and multiclassing. The argument is under the multiclassing rules that multiple abilities of the same name do not stack, (and it was even FAQ'd that only assassin's sneak attack stacks) so why should sneak attack? The example given here was a rogue / slayer multiclass. I don't think sneak attack from multi classing stacks unless explicitly said, am I correct?

Thanks,
