First look on the training chamber. The Training Room is where heroes will probably gain most of their experience before exploring the lands and underworld. Generally, the room is crucial to preparing a force that can handle the opposition on a map, and the ongoing cost of training heroes is the largest drain on your economy. This room is considered one of the “basic five,” along with Treasure Room, House, Inn, and Library and is usually available for construction by default, without needing to be researched. Experience levels gained in training or combat will increase a hero’ combat stats.
