Warlock – “Expansion” [4th campaign, 2nd mission]

This mission didn't seem difficult to me. As they say, slowly but surely... I gradually defeated everyone, visited all the obelisks, and found where the Tear of Ashi was buried. The only thing is that the pink key I received is basically useless. Well, I went through the keymaster, so what... there's nothing important there. And I always look for the Tear of Ashi like this. I look at the map to see where this area is located... aha... a stone road, a tree... a mountain. I click on some point on the map and look at the treasure map; it displays the hero's trajectory if there is something in that location. And I didn't have any trouble searching at all)))
