A greatsword requires two hands to wield. It is the largest type of sword, considerably longer and heavier than a bastard sword or a longsword. The greatsword is typically used to kill horses, and for executions, though rarely for regular combat as they would be far too cumbersome for the average person to wield. However, particularly large people might be able to wield a greatsword as a bastard sword.
Size
A good estimate for the size of a typical greatsword would be 1,5 metres (about 5 feet). The size of the sword depends on the person wielding it though, so swords wielded by exceptionally large people may even exceed 1,8 metres (roughly 6 feet). It should be noted that because Ayleid Steel is considerably lighter than common steel, Ayleid steel greatswords are likely to be larger in general.
