Kael or Athel first. Do you have either of them booked?

We're looking for champs who do as much as possible early when we 6 star them, and the starters do that. They'll be good in campaign farming, Dragon and Clan Boss. I prefer Athel, personally. If you have one of them booked, go with that one. 

We need to stop taking several champions to 5*, and focus on taking a few to 6. Dark Athel is one you can stop building out for sure, as she doesn't do too much. 

Kael!

all you should be concerned about at this point is campaign farmer brutal 12-3.  Which Kael is your best option.  You can use him in other content as well.

Kael

Also, who is on your lifesteal set? Ideally that should be on your main champion you plan to 6 star - will make it so much easier for farming.

Nobody I tried to max out the critchance on dd

Topic can be closed my 1 6 stars is kael second will be ronda

Good choice.
