[ACG] Merciless Butchery and Extreme Prejudice feats not available to Investigators

[Barachiel Shina]

I am looking at these 2 feats and the prerequisites require Studied Target class feature AND +3d6 sneak attack.

But Investigators do not get sneak attack. And none of their archetypes grant it either

Are these only meant for multiclassed Investigator/Rogues?

'Studied Target' is a Slayer class feature, Slayers get sneak attack.

Ah ok thanks for clearing that up. I must have confused it with Studied Strike.
