Can someone explain the giving pets a torch thing?

Oggok cleaver on a low level pet will hit for 80s but it’s kinda finicky. There are however a few good weapons that will make pets starting at lvl 1 to hit for 60+ and others that they will just eat! There is no list of these weapons on wiki that I know of but it seems most weapons with a damage bw 20-34 will work on any level summoned pet and pet will do 2x damage with it.
