What FrauBlake means is:

crafted weapons usually auto-level, so you get appropriate stats on your weapon, regarding the player level.

These are the ItemCombos entries:

Code
use category Dagger on object WPN_Branch_A with transform code Destroy1Transform2 parameters WPN_CraftedSpear_01,0,0,0,0,0,1,1 requires Crafting 1 autolevel 1 autoValue 0
use category Dagger on object WPN_Branch_A with transform code Destroy1Transform2 parameters WPN_CraftedSpear_02,0,0,0,0,0,1,1 requires Crafting 2 autolevel 1 autoValue 0
use category Dagger on object WPN_Branch_A with transform code Destroy1Transform2 parameters WPN_CraftedSpear_03,0,0,0,0,0,1,1 requires Crafting 3 autolevel 1 autoValue 0
use category Dagger on object WPN_Branch_A with transform code Destroy1Transform2 parameters WPN_CraftedSpear_04,0,0,0,0,0,1,1 requires Crafting 4 autolevel 1 autoValue 0
use category Dagger on object WPN_Branch_A with transform code Destroy1Transform2Boost2 parameters WPN_CraftedSpear_05,0,0,Weapon_Large_Damage_Mod,0,0,1,1 requires Crafting 5 autolevel 1 autoValue 0
use category Dagger on object WPN_Branch_A with transform code Destroy1Transform2Boost2 parameters WPN_CraftedSpear_05,0,0,Weapon_Large_Crit_Mod_Late,0,0,1,1 requires Crafting 5 autolevel 1 autoValue 0

As you see all crafted spears have autolevel 1, and this also means that their requirements increase, depending on the player's level.
