Just now, thespaceinvader said:I very much doubt they can block, they're Devices not ships.
So you think a ship will go through it, completing its maneuver as if nothing happened, but the droid will have to roll the attack die? That's a fair guess.
On the other hand, I'd absolutely risk rolling an eye if this thing does keep ships from completing its maneuver/taking an action. It does seem too good for what it will likely be worth. The ability to block adds, I'd say, maybe 8-10 points to the cost of the upgrade.
