You haven't mixed anything up! It's much more fun this way ;)
In general, they should charge more money from the treasury or force you to fight rusty dragons for the most useless artifacts.

What a pervert :DDD So, you should have to fight for the Blade of Armageddon once a week, like for the Shield, but with 30 Anti-Christs?=)) And for the "father" of dragons, Azurick, and for the Alliance of Angels, you should fight with the Archangels?=) A pervert through and through :DDDD I really liked the new Shield of the Fiery Ogre, the Amulet of Life is not bad, not because of the fairies, but because of the HP bonus ;) Hmm... well, all the Warlord artifacts are cool, except for the Map of Luck (it should have been called the Map of Bad Luck xD) and the Hourglass of Ill Omen (Asmodeus). Hourglasses are rarely in demand... A bonus with money, units, experience, and knowledge is always welcome ;) It would be even better to have an option with commander artifacts, where you can endlessly customize secondary skills ;))
