When you and your bonded ally both ready an action to attack the same target and choose the same condition for the readied action, when you and your bonded ally make those attacks, use the highest of the two attack rolls (each attacker applies her own modifiers to the roll). If you and your bonded ally both hit the target, total the damage for both attacks before applying the target’s DR or energy resistances.
In starship combat, when you and your bonded ally both attack the same opponent in the same round with a direct-fire weapon, use the highest of the two attack rolls (each attacker applies her own modifiers to the roll). If you and your bonded ally both hit the target, total the damage for both attacks for the purpose of determining how the target’s Damage Threshold affects the damage.
