First of all, the butcher's main strength growth depends on his third skill, which means you have to kill more than N monsters to play your magic skills! But then again, when you kill monsters, your level will also increase. So I don't think your level 20 can reach the physical value you said. But after reaching the highest level of 25, his power growth is infinite, which will be calculated according to the number of monsters you kill.
Homeowner, you are not clear enough, whether it is in the case of naked or in the case of holding.
You can't grow on your own without equipment!
But if it is equipped, for example, a butcher is equipped with six godsons, hehe strength is: 35*6+ own physical value =? Needless to say, in this case, right, homeowner?
