I currently have a CTR VHIGH Blitz Needle. At level 10, that's CTR MAX.
I also currently have one Elite Trueshot Module (+DMG GUN MED) and a Swiftstrike Buckler (+ASI HIGH).
That means on my Blitz, I currently am at.
CTR MAX
ASI HIGH
DMG MED
I'm thinking of going to whole nine yards. Going for the fastest possible downtime between charged blitz needle shots with the highest possible damage increase. For that, I'm thinking of getting another Elite Trueshot Module (+DMG MED), a Nameless Hat (+ASI MED), and a Shadowsun Slicker (+DMG LOW).
