Yeah, i meant wonders.
Available to: Hordes of Chaos, Beasts of Chaos, Chaos Dwarfs, Dark Elves, Skaven
Available with: New tech, preq. Demonology. Storm of Chaos or Chaos Undivided are two options.
Obselete with: Greenskins
Requires: Chaos government (perhaps Warpstone?)
Like the Knightly Orders for the Humans, my plan proposes four Chaos Temples (one for each of the Chaos Gods: Khorne, Nurgle, Tzeentch and Slannaesh), each spawning the corresponding Greater Daemon
The GDs would be spawned a lot less frequently (i think mrtn worked it out as being every 32 turns, based on the shield cost)
The only problems i can see with this is that there are less races that would be able to build the Chaos Temples than civs able to build the Knightly Orders, and having Greater Daemons spawned may make the late game unbalanced.
another problem is there is still one Greater Daemon missing, the Lord of Change. so this wouldnt work unless that was made
since the greater daemon is currently the chaos "dragon" unit, i propose either a chaos dragon (two or more headed beastly beast) or chaos spawn to replace it. this would require further units to be built, however...
