Though the Restoration of Erathia manual (page 91) claims that Black Dragons hate Giants, this is not true in the actual game—there is no hidden bonus or penalty in battles between these creatures.

It is not possible to recruit upgraded creatures from adventure map dwellings—except for Iron Golems, which can be directly hired from the Golem Factory.

Peasants cost 10 gold and Halflings cost 40 gold, but both are recruited for free from their native dwellings. The listed price only matters when they appear at special locations like Refugee Camps or the Portal of Summoning.

It is not possible to find Sharpshooters, Enchanters, Azure Dragons, Crystal Dragons, Rust Dragons, or Faerie Dragons in a Refugee Camp.

Sacrificing only Peasants at the Altar of Sacrifice yields no experience, regardless of their number—and the altar won’t accept Peasants alone; you must include at least one other unit.

During a siege against an AI, if all arrow towers are destroyed, repeatedly casting Earthquake will eventually obliterate the enemy’s upper‑right unit stack—no matter how large it is. The stack’s graphic remains on the battlefield, but its unit count vanishes. This behavior is a game bug.

If you receive a weekly or monthly +5 growth bonus of unupgraded creatures from a dwelling you’ve already upgraded in your town, the bonus will not apply.

Only Conflux and Inferno factions do not have a hero who specializes in the Eagle Eye secondary skill.

Using the Fly spell or equipping Angel Wings, you can hover over a town and press the space bar to block its gates.

Despite the fact that War Machines like Ballista, First Aid Tent or Catapult are not used during creature bank or shipwreck battles, the Ammo Cart still works—it provides unlimited shots for ranged units.
