Added the bug. Would be nice if we got some dev or mod acknowledgement on the bugs thread, but having it better than not having it I guess!

I suggest going to

sessions\addon\ses.kfs\medals.txt

and changing all instances of "viking_army_killed" to "undead_army_killed" so that at least you have a working medal at least.

I just read the manual and there it states "An Award for the Vikings for detroying hostile armies...".

i have 10 vikings killed. i dont know how

but im at demonis now!

I'm pretty sure it's just getting your viking unit to get the killing blow on a stack. I'm sitting on 7/10 right now.

.... You all noobs as i see, Valhalas messnger how name says, so tried killed with valkyre when got first in second island. Killed with vlakyres that treasure skill troop and got 1/10 have a nice day. They transleted wrong not wikings but with valkyre.

Yeah that could be correct too about killing with valk move since I hadn't really checked the medals and just checked after recently getting first valk.

Edit: After testing that it's just related to killing enemy viking groups. Barsuks, should be careful when you act arrogant otherwise you might look like the fool when you turn out to be wrong...

Valkyrie is not the option.
 

I just killed 3 groups in a fight, and also ended the fight with the Valkyrie to clearify. Still 4/10 which I had before the fight. =/

I had killed 6 Viking enemy troops in a row. In each battle i killed a stack of the unit "viking" (not to mistake the troop berserker, they don´t count, all other viking enemy units also don´t count) with a attack of a valkyrie.
Not a Viking rage attack from the first row. They don´t trigger the medal. You can use any attack from the second or third row (the "valkyrie" attacks). 6/10 so far after these fights.

Each fight you can get only one timer of the medal, i have killed 3 stacks of the unit "viking" in one fight with a valkyrie, but it only counts as one.

I hope this is a bug and it should be "any" enemy viking unit and it is wrong that it had to be the unit "viking". Or there are many battles against vikings later:)

Just killed a Viking unit roaming the map and it counted as 1. Sounds like it´s totaly random since this kind of thing didn´t count for others.
