I just noticed the exact card text reads "When an enemy ship inside your firing arc at range 1-3 is defending, the attacker may change 1 of its hit results to a critical hit result."
So, I noticed moreso that it doesn't say "another attacker", so could that potentially include A'baht himself? Does he essentially get Gundarks ability but at any range, or do you think this will be in the errata? Because technically as it reads now, his own attacks are fair game.
