About the most minor tweak you could imagine

[Endoperez]

What is the first round knights use their lances in? The first attack in a battle? All the attacks in the first round (if quickened somehow)? Does the distance the knight moved affect the damage given by lance?
Is there a way to make a new unit having an attack like this? If yes, is there any kind of a requirement for a weapon this would be done with? That is, does this kind of attack only apply the lance, or can you define that a normal spear would be used in the first round?
