IF the boss battle EVER comes back up, from what I've read, the only way to take it down is with Ramming Speed. Most folks said they had three skill points on it. This may however be useless, depending on what changes they're making to the battle before it comes back on, but even if they change the Boss Battle, ramming speed is really nice for a quick getaway, or a quick way to
get to a ship you want to take down. I'd put the rest into treasure sense and wind catcher. But that's just me...
