Is there a set distance from each other, braziers should be set to be most effective? Can they be too close or too far from each other and cause reduction in firepower?

Thanks

The Blazing Brazier wiki page contains the formula. It is based on how many braziers are in range (about 23 tiles).

More braziers clustered = less damage PER brazier, but more TOTAL damage.

One Brazier isn't gonna stop anyone, "efficient" or not. Even with clustered damage it's barely enough to slow raiders honestly.
