- Main article: Buildings
Players construct a variety of buildings in their castles in order to achieve different goals.
Lords Online inventories come in two distinct categories: player items and hero treasure. Player items include speedups for building and research, bonus cards for resource bonuses, and item/resource generators such as gem packs or resource books. Hero items are called "treasure". Treasure includes armor, weapons, healing potions, runes, gems, and spell scrolls. Though the game is free to play, players may purchase various enhancements and upgrades in the Cash Shop using real money.
Various monsters inhabit the world of Mu. Low level monsters live in the Lair beside each castle. Outdoors on the map in hero mode individual monsters dot the terrain. Monsters are rated by recommended level. This number means recommended hero level, not player level. Monsters in purgatories are usually the level of the purgatory, but boss monsters in purgatory quests will be much stronger than the others.
It is possible to recall an offensive march within the first 90 seconds after giving the order.
Events happen occasionally, usually to celebrate or commemorate a certain holiday, such as Christmas or Hanukkah. These events usually introduce special features to the game, such as new maps, new quests, and/or modified monsters.
