I always thought the Shivermist Buster was the ideal bomb for the swordsman, but ever since I've been in a party where someone had a Voltaic Tempest, I was amazed by how effective mass shock is.
In your opinion, what do you think is the best haze bomb to bring if you're a swordsman?
Shivermist is still best. Shock is intermittent, enemies can still move and attack, and mechaknights can spread shock to you. Voltaic tempest is pretty great, but if you primarily want something to make your sword more effective, you can't beat freeze.
