Arcane Trickster Pre-Requisites

[AC81]

The game says you need 2d6 sneak attack to qualify. Does this have to be specifically from rogue or can you qualify using combinations of classes that grant sneak attacks? Any ideas?

You can use the PRC's we have that grant sneak attack that stacks with a thieves sneak attack.
Examples would be Wilderness Stalker and Ghost-Faced Killer.

It looks like 2d6 Death Attack, and invisible blades 3rd level bleeding wound work as well.

Same goes for Assasin's Death Attack.
