No. Many sets are actually not available in the Market at this time. Although there are many things available there at different times, sets such as Stun, Regeneration, and Frenzy can only be obtained from dungeons. 

If you want a Stun set, you will need to beat the Fire Knight's Castle for those artifacts.

In the heros section you got a suggestion for the best artefact to equip but they are all tje same. You got nothing for the other so we have to pay big money only to test if it’s better or not for the hero. Do you plan to add someting to indicate if thoses other artefact are good or not. Also the price to get artefact to the highest level are way to much. It cost me more than 1 million to get my artefact to the highest level
