How to defeat a Fatui Skirmisher - Cryogunner Legionnaire?

I hate fighting these guys in Inuzama because it'll be raining half the time which applies wet effect to my entire team and causes them to be permanently frozen by this guy...

Anyway, the first thing you wanna do when engaging the Fatui is to defeat the hydrogunner first because he can heal the others.

Then next for the cryogunner, obviously pyro is the most effective against his shields but if you don't have a good pyro you can also try geo. If you have a geo traveler or zhongli, you can generate a constant shield and just keep hitting him until he eventually dies.

If you insist on keeping your current team line up, then Beidou will be your best bet (I also use Beidou in my team as a sub-dps tank, so I would know haha). When he starts his frost attack, run away first and count to about 3 seconds, then approach him and activate Beidou's elemental skill. Try to time it so you get a max damage perfect parry. Then feel free to rough him up a little, but start running again when he readies his gun. Beidou's perfect parries deal so much damage that you should be able to kill him with a few cycles of the above steps. Most likely, he'll die before his shield goes down haha.

Good luck!

Despite the things SPArcheon have said. Keep in mind that Fatui Skirmisher's shield is different than other shield. Their shield can only be destroy by applying special element or deal a huge amount of damage(don't have a specific number), which is more than the HP of the Fatui. Pyro shield can be destroy by applying Hydro, Cryo by Pyro, Electro by Cryo, Hydro by Electro.

Other shield can be destroy by applying any of the reactions. You could think of that, the shield is a compose of elements. You could deal damage and break the shield, or you could apply reactions, because reactions will consume elements.

By the way, someone have tested, if you could freeze the one with Cryo shield(which normally can't be freeze by apply Hydro), and use claymore or Charge attack to cause Shatter, it will be even faster than using Pyro(If you could keep the rate of frozen) , because Shatter will consume the Cryo element in the shield(It doesn't work on Cryogunner, as I have said in earlier section.)
