I gathered a lot of vipers, and the pace was good. On the third turn, I found a control point, cleared out a bunch of treasure chests, but found nothing related to magic or shackles anywhere. As expected, the opponent attacked with 32 skill points and 240 mana. In one turn, they cast 128 earth spells, and I didn't have enough skill points or knowledge. With the mana I had left, I fled the battle, losing a lot of earth elementals and my entire army. After that, we ran around for a bit, and I decided not to prolong the game.
Thanks for the game!
