Players choose between three types of "hero" - ranger, warrior and mystic - with respective strengths and weaknesses. The heroes in the game win experience points by defeating foes – humanoids or monsters. The hero has a personal profile and can acquire titles on a weekly basis, which may offer bonuses. Players are encouraged to team up in a "Guild" and help each other in order to survive and prosper in the Ayarr Empire environment. The players control their hero which is the leader of their party of up to 5 mercenaries. Heroes and mercenaries can be specialized in one of 6 classes, which have different spells and abilities. Also, each member of the party can be equipped with items, which improve their attributes and make them stronger. By defeating foes and completing quests, the party gains experience and increases its level, which unlocks more skills and opportunities.
In Imperial Hero players are competing with each other in multiple ways. They can attack each other to plunder resources, they can participate in fighting tournaments, or they can defend the borders of their faction against attacks from other the other factions in the Border Patrol. The winners in the various PvP activities receive weekly rewards, based on their performance.
Players of all factions can trade resources, consumables, items and rare goods. This is done through the in-game auction house and the resource market. The economy of the game allows for the free exchange of most goods and savvy players can amass fortunes.
Players can organize themselves into guilds of up to 50 people. Guilds provide a way for players to communicate intimately, share resources and items between each other and complete common goals (guild quests). Furthermore, each guild can build their own Guild Castle, which is exclusive only to them. Building structures in the castle provides bonuses to all members in the guild. Guilds can raid each other's castles to plunder resources and damage buildings. Players participate in the raids with their own parties and are matched against the defenders of the target guild. Guild castles also have garrisons. These are multiple parties of mercenaries loyal to the guild and helping in the attack of other castles or the defense of the guild's castle.
