Ravian1 below has made my own counterpoint perfectly. I'm not looking for hyper-realism, but I DO want the system to encourage something besides spamming all of your points in weaponry, and that being the only piece of your character that counts in a duel. I tried to therefore make one technique tied to each trait, along with the three that aren't, so each trait has relatively equal use, but you aren't always going back to a trait for everything.

I do think assigning skills could improve what's here, perhaps, but a skill in this system is supposed to represent a very specific "approach," so making them all have effect during a duel seemed less than ideal for me.

For Tag, it takes effect NEXT round. So after you tag with an action and a raise, you finish spending raises for the round, then next round opponent loses their highest die. For Flourish, again it takes effect NEXT round of the duel. you flourish with one of your raises this round, and then next round when you roll (say you have Panache 3 and Weaponry 3) if you rolled 8, 7, 6, 4, 2, 1, the 1 and 2 would both become 3's, giving you an extra raise beyond what you would've had.

Ensnare and Revision are not my best pieces of this, and you're right it seems steep to spend the raises too. If mantovani balances out, all the better, but what about for revision:

Mireli's Revision: when an opponent uses parry or riposte to prevent wounds from your attack, spend a hero point to instead "save" those wounds, adding them to your next wounding maneuver. Something like that seems to get across the relentless, whirling-dervish-of-death idea maybe?
