No worries at all.
This one could go on for far too long on the topic. The HEMA group that tolerates this one is currently rebuilding some Messer techniques, beyound that, we are very acquainted with Silver, Lichtenauer, and Fiore. However, there are numerous oddities when converting from manuals to practical. One, some manual’s (for dueling specifically) are either incomplete or deliberately flawed. Two, some have satire we barely catch due to loss of context. Three, a few of them have techniques that are perfectly viable with modern, through tempered blades. These maneuvers would be very questionable with pre-modern steel of anything but the highest quality we have found. So there is an excellent chance our superior armaments allow us to use a technique in a way it was never intended.
That is a huge danger of reconstruction from broken lineages.
Military manuals are more reliable, as the orders of the individual soldiers or even formations are not nearly as secretive as dueling is. The actual strategies and especially blue print equivalents of fortifications are much more prized.
Of course, what is used in a duel may be near useless in war, and the habits of a good soldier or knight are suicidal in duels that eschew the wearing of armour.
John Talbot, the English Achilles, the Terror of the French, died pinned under his horse when took an axe to his noggin.
Takeda Shingen’s death is a subject of wild speculation. A personal favourite being that an assassin stabbed up his fourth point of contact while he was engaged in a #2. Given he had well documented gut troubles (possible IBS, possibly any number of complications due to his rumoured prodigious drinking habits) a sudden pain while engaged with effluvium would be nothing out of the ordinary.
Great warriors die to misadventure all the time. Likewise, one unlucky circumstance can end a duel abruptly and with a disappointment.
Many knights passed to the “heat of battle”.
If one wants a taste of the “Heat of Battle” put on a full set of sweats and biker leathers, then 'Murikan Football pads over that. With arm and leg weights. Now practice boxing. In the Summer. No hiding in the shade. With more ale/wine than water to drink.
Medieval gear was better fitted than that, but aketon/gambeson + mail/brigandine does not breathe. Especially as much of it was double layer wool or canvas with padding between those layers.
But that’s a digression.
Bringing it back to game, this one would love to see more “improvised weapons” such as broken bottles or metal tankards, especially as off hand weapons. Especially not as legends or rare drops. Instead the broken bottle can be crafted by hand. 1 glass flask + 1 stone. Low durability, low penetration, but causes bleed.
The tankard could be reinforced at the blacksmith bench with an iron bar.
If we must make a feat to learn them, perhaps include them when one learns the fermentation vat? Or better yet they are unlocked the first time one drinks and alcoholic drink, adds the feat bar brawler?
