I made a Twitter thread about the realism of medieval fights in general, and the way I would envision thel in Zodiac Legion, with some cool pictures from the fencing manuals of the time.
I had a discussion about realism in game with some of my friends when designing
@ZodiacLegion
They argued that no one cared as long as the combat presented interesting decision.
However, I find it strange to have spent so much time on fantasy RPG, on PC or tabletop, and still be totally unable to imagine how an armored fight would look like. I think it is better to have the gameplay reinforce the theme, and for that, some realism is needed.
Sword poleaxes were not really a thing, but they make sense (and the author gives instruction for you to get yours done at your local blacksmith).
One issue I have with armors in movies or games is that it doesn't do its job at all. It either provides minor protection, or is even detrimental, as you can see with every character going helmetless.
This is what too much disdain for realism gets you.
which makes having a good idea of how medieval combat was pretty hard, as it is usually not a topic historians are really interested in, because the specifics of 1v1 combat has little importance in the large campaigns or battles they study.
So, it took me quite some discussions with my HEMA instructors, and some reading to just get a good view of how medieval armored combat worked. But this scene, from the movie "The King" is a good start:
The main issue here is that the fighters do a lot of counter productive moves, but their outcome is kind of realistic (in that they exhaust them and don't advance the fight). Armor was a very big deal, and plate was totally impervious to cut, and almost impervious to thrust.
That is why you see so many of the manuals focusing on hitting the weak spots of the armor with a thrust, getting your opponent to the ground, or disarming him. A strong poleaxe hit to the head still remains an efficient way to go, but it is very hard to do.
So the dreaded grappling rules came into play a lot at the time, because of how important it was to bypass the armor, but grappling with armor and weapons was a slightly different affair, as you would lead with blows or use your weapon as a lever.
A book I found very interesting about the matter was The Use of Medieval Weaponry by Eric Lowe:
https://www.aeonbooks.co.uk/product/the-use-of-medieval-weaponry/94108/
It goes from the sources (Talhoffer, Fiore dei Liberi, Licthenauer, ...) and adds the personal experience of the author when it comes to asymetric weapon fights to describe the flow of medieval combat.
I want to make armors play a major role in Zodiac Legion, and most weapons do "stamina damage" against armor, until the target drops prone (stamina would also double as wrestling HP), with finishing blows against downed targets.
