Does the Rogue's Assassinate feature (auto-crit on surprised targets) allow for multiple crits if you make multiple attacks that round, either through two-weapon fighting or extra attacks gained through multiclassing?
As an example: my 3rd level Human (Variant, TWF feat) Rogue-Assassin rolls high on his stealth roll, and gets up behind his target. With two daggers, he gets 2 attacks per round if he uses his bonus action as well. Do both of these attacks qualify for Assasinate's auto-crit feature?
That is: would I do 2 criticals for
or a single critical and a non-critical for
Additionally, if I gained the Extra Attack feature through multiclassing, would I get crits on all 3 of my attacks, or just the first one?
