FizMiG 5.2 Logistics. Features of movement on the map
One step horizontally (vertically) across open terrain (grass, earth, etc.) costs 100 MP, diagonally - 141 MP (exception - the last step; if the hero has at least 100 MP, they will be able to move diagonally - see section 2.3)
2.3. Last step.
If the hero does not have enough MP to move diagonally (141), but has enough for a horizontal or vertical step (i.e., 141≥MP≥100), they can still move diagonally, but only if there are no movement penalties (roads, army composition, and the Flight spell are not taken into account - i.e., the terrain penalty for the last step always applies).
