It's clear that the ideal route to the treasure chest from the explored area was the exit from the Inferno spawn point, which was located near the city. It led to an unclear path towards the enemy's secondary base. However, this treasure chest didn't seem particularly interesting, and the path to the second Necropolis secondary base, which took 3 heroes to break through, wasn't cleared, in my opinion, for no apparent reason. The path to the treasure chest near the Necropolis was very close, and it would have been logical for the opponent to go through the Necropolis exit to the empty treasure chest instead of going through the grass to an unknown location. The skill tree consisted of attack, tactics, defense, earth, and logistics – these were the first five skills. Any player would have taken earth, especially given the unfavorable position on the spawn point and the number of counters. Since he was going to get defense after earth anyway, he preferred to take defense and upgrade logistics, as they would have been more useful at that moment than an un-upgraded earth skill, which he would have gotten regardless. It's surprising that a player of that level didn't take earth immediately.
