Demon Slayers can freeze bosses.

No one understands the potential of this skill and its impact on bossing.
Demon Slayers are great bossers in general because they can ignore SO MUCH PDR. They have 50% PDR Ignore from their main attacking skill, that comes with +30% boss damage, then they have a monster debuff that is 15% PDR Ignore that can work with everyone in the map, along with the fact that it gives +20% item drop rate, -15% attack and +20% exp. Then there's that skill, Dark Bind, that can passively ignore 30% PDR. So the question is, why the f`uck wouldn't you take a demon slayer to Cygnus? Unless you're retarded or something.

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.
