So you are thinking something along these lines?Dueling sounds good, but from raw meaning this word - 1 to 1 fight - I'd add to second part about disadvantage "when you haven't another enemy in 5 feet from you"
Balance is a key point. I want something interesting, fun, etc. but I am not a power gamer (usually LOL) and think most characters are strong enough. But, I wanted to add something that is useful for all the styles but won't break the game. When you have time to check them out, if you see anything that you feel is just "too much", please share!I can't read it all for now, but these fighting styles aren't from official resources, are they? Look great, but little OP, maybe as higher-level improvement.
You absolutely need to have both active and passive characters options in the game. This is paramount, a key feature of 5e that enables different players at the same table, those who want to play a low-complexity game ("add this +1 here when levelling up, and it takes care of itself") and those who want a more tactical edge in having to choose what to use each turn.
yes that's perfect. I'm not good in English and was not able to wrote it as good as you. And sounds me "real" In 1to1 you are able to act much more free than you have to be aware with more hostile creatures.So you are thinking something along these lines?
"When a melee weapon attack is made against you, you can use your reaction to impose disadvantage on the attack. You must be aware of the attack to use this feature and you cannot have another hostile creature within 5 feet of you."
That's as good as a critical. Perhaps you could change the critical instead: "When you score a critical you roll one extra die."
It's about 42% as good as a critical if you're using a d12 weapon
and provide a style where d12 is actually a bit better.
There is a difference between complexity and power, however. If you want a more passive system, you can use the base feature for each style. For more complex play, add in the bonus actions and reactions. But, if you add them, by default you add power through those options.
To have a tiered-power systems that is passive and a system with options that without more power, you would have to have two separate systems completely.
So, I am using a "low-power-low-complexity" as the base and adding the action cost options for people who want more active styles with more features.
It's far better than that as it happens far more of the time.
