Step 4 – If need be, maximize the weapon’s damage by combining it with a “best-in-class” weapon
The point of this step is if your Late Bloomer is not already best-in-class (right at 15%), feeding it a best-in-class from any of the four brackets will bump your main weapon damage up to its maximum potential.
Best-in-class refers to the damage of the weapon relative to its bracket. Remember how a Late Bloomer is a weapon in the bottom 15% bracket of the possible damage range? There are four such brackets: Late Bloomer (0-15%), Random (16-35%), Normal (36-47%), and Early Bloomer (48-100%). Best-in-class refers to weapons that has the highest damage for the bracket it is in. In other words, any weapons right up to the 15%, 35%, 47%, or 100% mark is best-in-class for their own bracket.
Using the earlier example, if your level 1 Damascus Knife happens to be 175 damage, we know it’s a Late Bloomer, but also that it’s below the theoretical max of 180. This means when you level it up, it will scale accordingly and always fall behind another Late Bloomer that started out at 180. Now, if you feed it with, say, another Damascus Knife with 227 damage (best-in-class from the Early Bloomer bracket), it will bump your Late Bloomer’s damage up to theoretical max of 175, and it will scale up from there as you upgrade. Again, you could actually feed your main weapon with any weapon type of any damage bracket, as long as it’s the highest damage of its bracket.
