Hello, Two questions along the same lines. First lets say a ship with sharp shooter is shooting at a ship with bad weather fighter which gives +1 to concealment rolls. Would a natural roll of 5 then count as a six and allow it to evade the attack? or does it still not count as a roll of a 6. secondly, if you have a +1 to each die on say a gunnery attack, does this mean that a natural 5 counts for 2 successes like a six, or does it just mean (similarly to a -1 to each die) that a 3 also is a single success. Thanks.
For the game in general you add all the pluses and subtract all the minuses and then check for a minimum, so Sharpshooter and Bad Weather Fighter cancel out. Scheerluck is correct on part 2.
