Ehdd, don't forget Lemgem herself has a +4 to attack and +4 to piloting.
Guys, remember that [url]Lemgem shared that Ratrod's vehicle has an energy absorption barrier[/url], so we should only fire kinetic weapons at him. I presume that was shared with Velocity also.
Velocity, seeing Orsis ahead, turns their weapon to fire on his craft.
energy weapon vs Orsis: 1d20 + 7 - 3 ⇒ (11) + 7 - 3 = 15
Meanwhile, he continues to pilot with exceeding proficiency.
piloting: 1d20 + 10 + 2 ⇒ (17) + 10 + 2 = 29
