If I understand correctly . . . Tasha's Cauldron will introduce a new fighting style granting blindsight, and a feat that allows any character to take a fighting style.
According to the SRD, "A creature with blindsight can perceive its surroundings without relying on sight, within a specific radius."
That really opens up the door for some cool character ideas. Can't quite do a blind Zen archer (unless he's shooting reeeeeallly close), but a blind monk or swordsman type works great.
...
Tasha's Cauldron Blind Fighting has a radius of 10 feet.
It is a situational ability that can give you advantages in certain circumstances. Also with relevant warlock/Druid/Drow abilities etc.
But It is crippleware for creating a 'blind swordsman' Fighter RAW in 5e.
I've been thinking Blind Drow Swordsman. Being able to innately cast Darkness is both a good strategy for a blindfighter and one that explains how he got into this line of work. It would also presumably mean being able to trade away sunlight sensitivity with the vision, which both makes it easier to commit to the handicap for the power gamer in me and is evocative of how this character came to be dwelling away from his sun hating brethren.
Naturally he should become a samurai.
Blind Fighting's 10' radius does not even remotely offset the disadvantages in combat of willingly giving your character the blinded condition at level 1.
As you only have a 10' radius to see the world through. The PC literally cannot "see"/Locate enemy combatants beyond 10'. Think permanent fog of war outside 10' radius...
So if you slay the Orc next to you but 3 others will be charging the party, you have no way to react to, or "see" them (other than guessing) until they are within 10'.
That is a huge disadvantage in a sustained combat with other PC's if you are also Blind.
The 10' radius is an even bigger disadvantage out of combat. Your character can only react to the game world in a 10' radius. Needless to say, that is a HUGE disadvantage, that IMHO during regular roleplay renders the PC virtually unplayable.
RAW the
Traditional 'blind swordsman' trope is not possible in 5e.
It is something one would have to workout with your GM as a houserule.
As a DM the only way I think it can really work in a game is if the player picked the fighter or barbarian class, and it was understood that none of the druid/Wizard/Warlock workarounds to 'seeing' would be taken or pursued.
Then if the player took the Blinded condition at level 1, I would give them 'Blindsight' with a radius of
GM Common Sense. I would rule it as a type of
Eldritch Echo Location.
The fact that the PC still cannot literally 'see' is still a big in-game handicap, that would more than offset the situational advantages they would occasionally get due to being Blind, but having Blindsight.
And I would also take into account the views of the other players at the table for this as well.
Depending on what type of campaign I was running, I would have no issues if a player wanted to give it a go.
