A quick question.
I’m a little late to the party but it would help if you mentioned how you were leveling.
I’m pretty sure the two traits stack. I don’t see why they wouldn’t. One is crit chance and the other is damage. Mug is a very useful trait since it can be used to instantly proc your bas. venom when you steal. The 50% less fall damage trait is really up to you.
As for the last 10 points, you really can’t go wrong with Thrill of the Crime (Trickery V).
