uh did they change sneak attack to actual d6 rolls? originally it was 1d6 X/multi whatever
So it's not on the tooltip, but the sneak attack damage scales properly according to 5E rules. So 1d6 at levels 1-2, and 2D6 at levels 3-4, and it will jump to 3D6 at level 5.
I think that's what you were asking but I may have misunderstood your question. If so my apologies.
