The beginning was normal; Necrozim took Rampart, where nothing can be built, passed through the garrison, defeated the gnomes, and then the neutral creatures became stronger. Playing as Jeddite, I visited the black tent, captured the Inferno Enclave, built the Hell Gate, and gathered forces from two Inferno locations. To get the Seer (who teaches water movement), you need a shield (in front of the shield are two Black Guards and the Grey hero with legions). I did it this way: I approached one of the guards, waited for a turn, unlocked the guards, took the shield, quickly entered a one-way portal, emerged near the Inferno, and passed through the Hell Gate to the first Inferno. Grey followed, visited the tent, and took the Enclave, unfortunately. But, with water movement, I was able to move further, visited the purple tent, and just as I was about to defeat Blue in the Inferno behind the purple guard, Grey showed up and the game was over for the unfortunate Necrozim. There was nowhere to hide, I hadn't found the brown tent yet to escape through the portal, and the path to the boat was blocked by hordes of minotaurs.
