I don't want him to be a coward. He'll depart, but I want one more fight, and I want him like "severely injured" before he goes. It's not in Hydra's personality to just ru away, he'd like to die fighting. If I made him run away, it would contradict everything I've done with him so far.
Do you really wanna keep Hydra around over here? I figured he should depart. Everyone is gone, except him, now.
Live to fight another day. I actually have something planned with him in the sequel, and while there are a lot of Gold Tribe members that died, theres still a good 10-20 around. Once Galleon is dead, there's no point for him to continue fighting. The Order is destroyed. He should retreat, go back to the Order homeland.
It's not about where to aim. There is no weakpoints. There is no special spot to aim at. Just keep on attacking, follow my posts, you'll get the idea. Neptune weakened him pretty bad with his final attack, so he's slower, and isn't as focused. He also has a huge wound in his chest from the attack, where a lot of blood is coming out of.
