So if you have a maximum upgrade level of +4, I can drop you a +4 weapon but a +5 weapon will not show up as a lootable item for you.
Also, this is in regards to what the highest upgrade level your character has ever done. If you have upgraded any weapon to +9 that is the level your character is measured from regardless what you are using now even if you have destroyed the +9 weapon or what not.
You may not drop any upgrading material at all.
