Defensive gameplay and other tactics.

:smile16: Well, it wasn't exactly a tactical maneuver, but rather a funny incident:p
Yesterday, I was playing the "An Eye for an Eye" scenario in "Tribes of the East" as the Dark Elves. I attacked with 8 upgraded Minotaurs against 40 Golems. I didn't want to lose the Minotaurs, and I needed the resources (the enemy difficulty level is medium). I spent half an hour running around the Golems, keeping 5 spaces between the units (the Golems' speed = 4), while the hero shot down one Golem at a time. As a result, I won without losing a single Minotaur:smile08:

By the way, about prolonged battles. In "Tribes of the East," in Arantir's campaign, there's a mission where the finale involves forming an alliance with the Orcs. On the left, there's an Orcish town that seems impregnable at first glance, because it contains hundreds of Cyclops and a few other creatures. But by using the "Necromancer's Mark" ability, you can take the town with an army that is 10 times smaller than the enemy's.
To do this, first, drive the Cyclops mad; they will kill all their allies. Then, using Blindness, Vulnerability, Necromancer's Mark, and Raise Dead (and all these spells are usually already known to Arantir by this time), you can gain levels 3-4 without losing mana or creatures in this battle (provided you are still far from the level cap). This method was not discovered by me personally, and the topic was already raised in the "Walkthrough of the Tribes of the East add-on" thread, but I won't be afraid to repeat it, because, in my opinion, this maneuver deserves public attention.
