Summary
Boatswain Borga likes to follow up on his initial attacks, so it won't hurt to be ready to roll, in case you just land a block, and don't hit a riposte window. I've also seen him come back from the dead as a figment, while playing with a low insanity meter. Have your guard up for that, if you play with the bar empty, as well!
