As for the attack power you said, there is no change, it is all the same. For example, the 180 rifle is supposed to have an attack power of 1800, and the 190 rifle will have an attack power of 2300, both of which are standard. The added value is also a fixed value.
But in one case, there will be guns with high attack power and no need for extra ones. For example, a 180 ordinary rifle has an attack power of 1800, and some 180 ordinary rifles have an attack power of 2 100, but it is rare. I have one, which is of little significance, because it is too expensive to replace it with a legend.
Let's look at the cost again: upgrading weapons means upgrading non-legendary quality to legendary quality with red star (market price 120- 125), blue star (market price 550-580) or purple star.
If your equipment is excellent and you want to upgrade to legend, the success rate of using Red Star is 5%, Blue Star is 25% and Purple Star is 100%.
So it is cost-effective to buy finished products directly.
Don't believe the experience of smashing legends. NetDragon's game settings won't come like that. If there is a legend that can be shattered at a small cost, that person has made a fortune and he doesn't have to do anything.
If there is any way, the legend will not be so expensive, it is already the price of cabbage.
This depends on how you choose. You can smash it if you are curious. If not, stop.
