without the gui you can still change the chance:
"C:\Users\[YOUR-WINDOWS-USER-NAME]\AppData\Roaming\Brotato\user\bclw_config\bclw_config.json"

INFO: if you play the current BETA, the MODCONFIG mod that I use, is not working with the BETA right now
so you will not see the GUI to change the replace red weapons to legendary weapons chance (the 50% chance default)

@Varrgas 2.0

I added the option to set the chance to a value from 0% to 100%

I added logic to let the legendary have the same weapon type like the replaced one

When you play a character which should not have legendary weapons at all I advice to set chance for this run to 0%

nice mod, who work fine.

I regret that there isn't any configuration tab to chance the % to get a legendary, or some more complex formula because 50% chance is really big and I found a legendary in the 1st run just after installing this mod, a run without luck, and found it before wave 20!
It's working for sure

But when you have one, and because they all have 2 tags, it will increase the chance to find the same one, and because it's legendary, then it become easy to make a build with 6x the same legendary weapon.
I in fact did it with no effort before wave 30.

So be warned that the mod work but the chance is massive for end game

→ I also confirm what "Plajuck" said, the mod make possible to bypass some character limitation, like Knight, Ranger, Gladiator, Renegade and more weird, with Wilding (initialy limited to T2 weapons)

Also this is highly undesirable for Vagabond, as having 6 weapons and 1 legendary among them takes away 100hp

Looks like it makes possible to get ranged weapons for Knight with this mod (e.g. Gatling Laser). I guess this can be considered a bug as Knmight does not get ranged weapons otherwise
