In the first week, I farmed the respawn and broke through to the secondary areas. On the second week, I moved to the center, where there were very unpleasant clashes on the road with no way around; I barely broke through and reached the purple player, who was on a 127 double. Then I took Conflux from the pink player, revealed the location of the Grail, and started digging with 5 heroes. The Grail ended up being exactly in the last possible tile)) I dug it up on turn 141 and set up in Conflux. On turn 145, I cleared a max Dragon Utopia (Tome of Water, Tome of Air, Titan's Plate, and a red boot) — not the most useful with the Grail in Conflux, but the gold and the plate came in handy. On turn 147, I took the opponent's main town and then finished the job. I messed up before the final battle due a blown timer. I overthought my attack on the opponent with a scout hero in the swamp and ended up one tile short of breaking through his Armageddon's Blade on 1240 — plate + Orb of Fire + leveled scout hero). Oh well, I thought, and attacked with my main — I had a substantial troop advantage, and our stats were equal.
Thanks for the game)
