Weapon Crafting Mechanics
The Weapon crafting is quite complicated. Every weapon has an ID containing one number and one letter, A-Z and 0-9. A-Z determines what weapon it'll be and 0-9 will determine what type of weapon it'll be.
T2 + P6 = Z8
T = 20, 2 = B, P = 16, and 6 = F
It's cross adding so it'll be T + 6 = 26 = Z
Now for the other set that'll be the number value, 2 + P = 18. The # in the ID will only be one digit so it'll see only the 8 and not the full 18.
This means that the product will have an ID of Z8
