Movement on the adventure map depends among other things on:
Base movement is your movement before bonuses from Artifacts, Secondary Skills and Adventure map structures are counted in. It's counted in how many tiles you can move, and are based on the Speed of the slowest creature in your army at the start of the day. One tile's worth of movement is one step horizontally or vertically on Grass. Moving diagonally costs 1.4 tiles.
