Gold
In the upper area of the main menu or town square, the amount of gold you have is denoted by a gold coin with a spiral symbol in the middle. Gold is a very important resource and can be obtained from just about everything from the regular and end stage chests you encounter in the Campaign, rewards from events, portal rewards, PvP rewards and from the Shop and Honor Shops. It is relatively easy to amass but is also equally easy to blow in mass hero skill upgrades. Choose your spending wisely so you won't suddenly go broke.
Gems
This section shows how much gems you own. Gems are the premium currency of the game. It is used to gain various advantages like refreshing daily limits or gaining extra stamina. It is best to use these sparingly if you cannot afford to purchase a lot of gems since they can really help in most situations. These can be gained by clearing a campaign stage for the first time, completing certain quests, rewards for events and tournaments, & outright purchase of gems using real money.
Stamina
Stamina is the resource that is needed to challenge stages in the campaign. This resource starts very small at 20 and increases the higher your level gets. Each regular stage requires 5 stamina to play and 7 stamina for stages at the end of each chapter. This resource regenerates at a rate of one stamina per six minutes. You can also purchase 25 points of stamina in the shop for 25 gems. This can be purchased twice before the cost increases. The cost will be reset the next day.
Chatbox
This is where you chat with the other players. The game seems to revolve on a hidden channel system. Meaning if you disconnect or exit, the people you were talking with will most likely be on another channel and you will be seeing other players. In here you can view system messages, general chat with players only and no system messages, guild chat if you are in a guild, or just choose to see all messages.
