Demon Slayers can freeze bosses.

I'm going to assume you boss, as you have high level characters, and are pretty funded. That said, I would expect you to understand that bossing has a great deal to do with WHO you know. I know a lot of high level very strong players, but would I take them on my run just because of how much damage they do? Absolutely not! I only take people on my runs that I know and trust. Does that mean that I may not be able to kill the boss the absolute quickest? Yeah, it does. But does that ensure that only people I can trust, can count on, will be on my runs so I never have to worry, not even a little bit, about some jerk off jacking loot? 100% yes.

I don't know how it is in Windia, but in Khaini, trust is a big thing on boss runs. That isn't grown on trees, or ingrained in a class innately. So, feel free to take any random old Demon Slayer to YOUR Cygnus runs, but then don't complain if he jacks your loot and takes off with it.

I already answered this a few posts back.
I'll say it again.
Chances are the people I trust will be making one of these characters anyway, so that isn't my problem. I'm positive this applies to other worlds.
