The questions are unrelated.
First the storm quality on page 117. If I'm reading it right then the storm bolter on full auto gives you:
- 1 hit with a success.
- 3 hits with one degree of success.
- 4 hits with two or more degrees of success as you hit the max fire rate.
It just seems a bit odd that it gives an odd number of hits until you reach the maximum fire rate. Am I reading this right ?
Also is there any way to upgrade crew quality (pg 193) after ship creation ?
For the starting ship I haven't found anything. If the PCs are buying a new ship, it looks like the quality of the crew would alter the SP cost of the ship, and thus alter the roll.
