===Elevation===
No battle is ever truly fought on an even playing field (in this particular case, we're focusing on the the literal sense). From small hills to towering settlement walls, units may find themselves looking down upon the hapless masses crawling their way up the slopes, exhausting themselves over every inch gained, or they might desperately find themselves assailed by a hail of arrows from on high, well out of their retaliatory reach.

Elevation can play a significant role over the course of a battle. Units traveling up hills not only move more slowly (thus reducing charge bonuses), but suffer increased fatigue gains (up to 150%) and deal less damage to enemies fighting above them (up to 30% less). Conversely, enemies charging down hill lose less fatigue, do so more quickly (increasing charge bonuses) and deal up to 30% more damage against foes below them. The benefits/consequences aren't just limited to melee infantry however. To no-one's surprise, firing at enemies beneath your position confers a substantial advantage; not only does this allow your archers/gunners to shoot over potential obstacles, but it also gives them up to a 30% damage buff against their targets as well. Should your archers or gunners find themselves at the base of a hill or wall, not only do they suffer up to a 30% damage reduction, but their shots are far more likely to be blocked by battlements or terrain, wasting precious ammunition. These percentages are calculated entity to entity and based on the relative slope/height difference between the two (depending on the terrain, two different entities in the same unit might deal more or less damage than each other based on how they're engaging the enemy).
