Hooray, I completed Ira The Mage. Even though I used hints, I managed to finish it on day 26 with 1 death and 4 artifacts. And judging by the comments on maps4heroes, I'm not the slowest, as some people closed the game on day 27 =)
I'm curious, what's the point of the quest for the diamond golem with negative gold? And I still don't understand how to complete it.

The map is mind-bending; I recommend it to everyone who wants to improve their gameplay. The only bug the map requires is using the berserker glitch, but otherwise, the entire game relies on fair tactics. For me, this is a "good" Chinese map where everything is based on mechanics, and you don't need to learn how to use mass blindness and other glitches.
