At the end of the first mission in the Kindred Fire campaign it says to spawn a unique elemental, when doing so do I still obey group limits?

EG: I play solo with 2 heroes and according to group limits I only spawn one minion elemental.

Do I only spawn the one minion? Or do I always spawn unique monsters as masters and ignore group limits?

Follow as the app says: spawn a unique master elemental, ignoring the group limit. The unique monsters that spawns in the app are usually the master type.

Yes, I take it as you only spawn the single unique monster. If I recall, when you do spawn a group with the unique monster the app says something to the effect of "spawn x monster group with the master monster being a unique monster y".

And I as I had asked it here before, when the App asks you to spawn a special creature (the master monster of a particular monster type), do only spawn its figure, not the entire group (master+minions) even if the App does ask you to defeat both the special monster and the group (I don't know if they did correct it or not)...I had had the problem with the mini campaign during one of the side quests.
