Legendary Dwarf (Jalis) is the first legend you get access to. Legends determine what utility skills you have available.
The 50% thing with the arrows shows your energy gain/loss. Under normal circumstances, you gain +5 energy per second (capped at 50 out of combat). Various skills spend that energy. There are also upkeep skills that have a cost per second that will be shown by those arrows.
