Walkthroughs for custom maps.

As I understand it, LordL wanted to know about a specific situation on a specific map. I saw his question posted today on maps4heroes.com. I don't know why he didn't just ask here directly. I remember that in the discussion about the Marlo Stanfield map, a solution to this problem was already described. In fact, the question was asked there, under his comment:

"First Blood" 2.5
I completed version 2.5 in 57 days... The most interesting part was removing the Sphere of Inhibition from Jelu. I had to put some thought into that.

Since no one has answered LordL yet, and it's difficult to find the exact information in the forum (I don't remember what the map was called in those posts), I'll describe the general principle, as far as I remember: you need to "lure" the enemy (by sacrificing your own hero) with artifacts that will be more valuable/desirable for the enemy (in terms of numerical "value" - not to be confused with the price in gold), which will encourage him to remove the Sphere and equip other artifacts. As far as I remember, composite artifacts like the Sniper's Bow or the Wizard's Well will work. That is, in order to use those other artifacts, he will have to remove the Sphere to free up the occupied slot.
