Dark Souls II Boss Guide: Flexile Sentry
You’ll find this guy on the pirate ship. I was playing a highly mobile character so I literally beat this guy but walking up to him, waiting for him to swing, rolling away, then punishing him. I just do this over and over again. That’s it. If you summon the swashbuckler lady earlier in the level and keep her alive, she can help in this fight as well.
