Ice Acolyte requirements?

#1

Just wondering about how I can unlock Ice acolytes. I’ve unlocked nearly all other units and have both Roxie and Nash at level 8, but I’m stuck with Kuro level 4 because I haven’t unlocked ice acolytes and so I can’t upgrade. Is it just one of the last units you get from expand your army quests? Or have I missed something important?

#2

Units generally are randomised so there’s no real exact science in obtaining them… of course with the exception of time warp units.

#3

I had to get past that milestone with Kuro by buying Ice Acolytes in the daily deals and then trying to find more there and by making requests for them with my guild.

#4

Ice Acolytes are a part of the Expand Your Army Quests.
