Which combined artifact is the best?

It's strange that not much has been said about its power. And if the starting castle is also a Conflux, then that's your first move. You need to slow things down, and then deal some damage to the enemy with Armageddon. It's quite strange that Armageddon is a level 4 spell, in 1 and 2 (I'm not going to talk about 4 and 5, not for fans of the third game; these are different games). It's a level 5 spell. But in general, each artifact is good in its own way, for example, the Mage's Well, the Horn of Plenty, and even the Mage's Ring! The Legion Statue is generally great – you gather it, put a hero with it in the castle, and the main thing is to have enough money! And the Titan's Thunder for a warrior hero?
P.S.: Everything written above is IMHO; they are all good for certain circumstances.
