So Torches, easy to get, help in the dark and the best non-magical 1 handed in the game.

First, its damage is 2d4 which is much better than 1d8.

Second, it has the light quality that means that it can be dual-wielded without a feat

Third, it is a torch so it allows you to see in the dark

Forth, it can be used by everyone

So, in conclusion, you have a weapon that is better than a martial weapon. That can be used by everyone who doesn't use dex as their main stat.

So what is the fix, well simple 1d4+1 fire damage and remove the light quality. then it will be just slightly better than a dagger and worse than everything else.
