The table contains data that I collected by testing (several times). The number indicates the number of cells (arrows) that a hero can move during one day. Moreover, I found out that heroes with scouting skills tend to move 1 or 2 cells further than usual, and I did not include these conditions in the table, as this happens (quite rarely).

Judge for yourself, the Stronghold and Conflux are simply travelers. :) Thank you for your attention, don't judge too harshly. ;)
