Jupp, window is down for Arthur's attack.
But actually the shotgun blast already had the -3 figured in: Base damage 13 -3 from spread and +2 from flechette ammo
Whenever there is a question about Smartness of pilots, you roll pilot x2 to determine how good it handles the situation:
Arthur tactics (Pilot x2):
10d6t5 2[10d6t5=3, 2, 5, 4, 4, 4, 2, 3, 6, 2]
I'd say he just keeps firing without changing anything, targeting the barghest in the lead
Simple action: Isaint runs rounds the corner and tries for another shot
AGI 7 + Skill 6 + Smartlink 1 -0 (Adept Centering/ Running -2)
Shoot:
14d6t5 3 [14d6t5=4, 6, 3, 1, 3, 5, 4, 3, 2, 4, 4, 1, 3, 6]
Yeah, not particularly impressive.
Simple action: Attribute Boost BOD:
Body Boost:
7d6t5 3 [7d6t5=6, 2, 6, 4, 1, 5, 1]
Free action (nimble fingers): Stash gun
Free action (nimble fingers): Ready now fully deployed rifle
Since he wasn't attacked by the sonic rifles last round and the grenade didn't actually land (due to Rick being awesome) he won't need the interrupt, but instead will now go on full defense against both the rifleman and the Barghest
Defense 1:
24d6t5 9 [24d6t5=3, 1, 4, 5, 4, 1, 4, 3, 6, 4, 4, 6, 1, 6, 1, 1, 1, 5, 2, 3, 5, 6, 5, 5]
Defense 2:
23d6t5 8 [23d6t5=5, 2, 6, 4, 6, 3, 3, 6, 2, 1, 3, 3, 4, 3, 2, 5, 6, 4, 3, 4, 5, 3, 6]
This drops his Ini down to 12
Arthur: Simple Action: Aim
Simple Action: Fire full Auto Salvo
Arthur shoot:
12d6t5 6 [12d6t5=5, 3, 6, 6, 1, 5, 4, 4, 3, 5, 1, 6]
Wow, this drone surely is pretty accurate.
Since the target is likely still at medium range, damage is 12 DV AP +4 Defense -8
