Here are the regular attributes that can be called: vehicle_ac vehicle_dt vehicle_speed vehicle_keel vehicle_crew vehicle_cargo vehicle_airquality vehicle_cost For repeating attacks, you'll need two parts: 'vehicleweapon' is the first part of the reference (instead of 'npcaction'), then the attribute portion from this list: npc_roll_output name quantity attack_range attack_tohitrange actions_taken--silent attack_onhit attack_flag description So you'll need %{selected|repeating_vehicleweapon_$0_npc_roll_output} I think that's all of the attributes, but I might have missed some from a quick glance.
