they should do a faction wars or campain for only blood troops 

So is this going to be one of those deals where if you don't have a specific champion, you're not going to be able to complete it? This game already has enough roadblocks in Marius and Ramantu missions, why would you want to add more content that only a certain group of players can do?  

What are blood troops? 

There looks to be several champ options and even gear sets like Merciless to help complete most of the tasks.

Of course, like original faction wars in 2020 with the limited champ selection at the time, it doesn't mean it will be easy. Gonna be doable but challenging for a lot of us, I think. :)

Okay I think the hard mode is gonna be ridiculous mode. I've been playing for almost 5 years I'm level 100 I've completed the regular faction wars couple of years ago. I can't make it through the very 1st level of shadowkin faction wars. That's right Level 1.

That was the biggest issue I mentioned earlier. If you don't have a specific champion, you are not going to be able to complete it ( Road Block) As far as trying to use an armor set for the stuns with the masteries is a joke with their resist being so high. I tried three times and got an average of just one stun a run.

Does the undead have a champion that casts Sheep?

No, they don't have a sheep champion. They can only "cast it" through polymorph blessings

For me, I was able to beat it using lady mikage, ninja, and toragi (and genbo and a very low leveled buranguri). But i agree that faction wars hard is incredibly difficult. Shadowkin is one of only 4 factions that i'm able to get pass stage 1. 

As far as I know, only two champs can cast sheep and thats Armanz and Sun Wukong.
