Cripple Barrier is horrible unless you for some reason want to spend 60 JP maxing it out.
I don't know why none of you swear by Throw Sword, it's easily one of the best crowd clearing Swordman skills there is. It's a good contender for DPS next to Penta Slash, Spirit Swords and can cancel bullets, which make it good for evading stuff like when using Leap Smash and Mangling. Only disadvantage Throw Sword has is you can't attack while you use it (for obvious reasons) but you should have decent timing to know when to use it. Sadly I still have a bunch of retarded deaths as a result.
Also, am I becoming paranoid or bosses hit you with a lot of non-bullet stuff when you're right in their faces? Claw swipes, tailslaps, the like. At the very least bosses have the weirdest hitboxes.
Oh and lol me pumping CHA for that lvl20 artifact sword.
Most of the bosses use their appendages/weapons to attack you WHILE shooting you at the same time so they do it regardless of whether or not you're right in their face. The first annoying instance of this is Stair Bridge (yeah lots of annoying firsts in Bifrost, I fucking hate that area) Stage 3's midboss, who throws his staff at you while doing stereotypical circle bullet spread. If you get hit by the staff's wonky hitboss, you will be dead for sure.
Regin's Destiny is a waste of 70 CHR, which I'm definitely sure is a typo or bug. :/
