Knight at Arms
If the looter with a spork get a clean stab on the horses face then it should absolutely rear the vlandian Bannerknight.Mechanical changes also apply to singleplayer/captains mode though - and no one wants to see a Vlandian bannerknight get reared by a looter with a spork.
That’s literally just how Spears work in Mount&Blade games.
This isn’t a total war game where we are all just stats and formulas whacking at each other. The entire point of the combat is to be skill based and not yoloing into a spear is a skill.
