Walkthroughs for custom maps.

I read about how to remove the sphere from him and even tested this theory myself. It worked. But Jelu with the sphere and Jelu without the sphere are, as they say in one city, two very different things. Removing the sphere immediately opens up a space for creativity for a skilled player. This is what Marlo Stanfield demonstrated in his video.

Generating blindness is probably possible, but unicorns don't blind every time anyway, and here you would have to do it every round. Considering that in the early stages our small army will deal relatively little damage, there will be too many rounds. In my opinion, implementing such a strategy, if not using some tricks, will be difficult.
A more realistic way to defeat him with the red sphere in the early stages is to use "Bribe" ten times. But this will require too much money.

In general, it's not clear why the author added this red sphere? In its original form, it was quite playable with a nice speedrun.

Apparently, he decided that this character was not challenging enough to beat. If we leave the speedrun aside, then this is, in general, a quite reasonable complication. It's a kind of skill check for the player. An experienced pro will find a way to defeat him even in the early stages. Less experienced players will also try to remove the sphere from him, but then they will give up on it and start looking for a way to defeat him with brute force. Well, and most, I think, not finding any acceptable solution, will simply let him die after 7 days after losing his last city and will not receive any reward. So, I rather support the author in this action.
