So my friends and i were playing the new bespin campaign last night, and I ended up as the imperial player and i chose the new class deck. I took the card "stealth" ("melee attacks targeting you require 1 or more accuracy to not miss") along with "shadow armor" ("exhaust this card when an attack targeting an imperial figure is declared to apply -1 damage, -1 surge, or -2 accuracy to the results.

at one point, I had a hidden royal guard with "stealth" attached and would declare shadow armor for -2 accuracy, and davith declared an attack. he would need 5 accuracy to hit my guard correct? That is how I read it anyway. WE were uncertain as to the interaction but I believe it was played correctly.

Yes. The modifier(s) from Hidden and/or Shadow Armor and accuracy from dice and other abilities are calculated, and Stealth requires that accuracy is checked in the Check Accuracy step also for melee attacks.
