Hall of Heroes
At the Hall of Heroes you find all your Heroes. There is information about them and you can improve their Gear in various ways.
Hero Info
In the Hero Info tab you find an overview of all your heroes. Their attributes, abilities and gear. The main attributes can be switched between basic attributes and adventure attributes. By default it is showing adventure attributes, which means the attack, health and armor listed is the ones your heroes have on the battlefield. The upgrades and levels you purchased with gold is included in the listed attributes. When you switch to basic attributes, the listed attributes will drop a lot. But it is still much higher than the base attributes that is shown here on the wiki. This is because gear, research, upgrades and experiments are included in the sum.
Hero Description
Here you can see what class, attack style, specialization and resource the hero is or is using. These come in handy as later in the game you find researches and upgrades that only improve a certain group of heroes. You also find the story of the hero here.
