Explain Chex Mex please, someone, anyone...

Just get ready for lots and lots and lots of tries.... Many in my guild do 50-100 runs before it the setup is right. That isn't explained well in the video.

You need:
1. A run with a sword with crit damage buff (you oftentimes get runs with none of these)
2. Han has to crit that sword with his initial attack
3. When the swords attack, Han cannot be hit, or at least not debuffed (at all)
4. When the swords attack, Chirrut cannot be ability blocked
5. When the swords attack, if they stagger someone (other than Han, see #3), that person cannot be hit by a different sword afterwards.
6. After the swords attack, CLS has to crit the sword that was damaged (it needs to be dead for deathmark to work)
7. When Traya goes, she cannot isolate Han

So if all of this happens, THEN you get to try the final run. And in the final run, Han dodges all the time. So if he dodges any number of times, time to start over.

I've had guild members spend over 2 hours on this and still end up with a subpar run.

It is by far the worst time I have ever had in this game in the past 2.5 years.
