Maybe you add personal items to drop from some [quest] Besses in eslant somethink like :
[Quest}Golem - personal sword +7
[quest]Harpy - personal dagger +7 and Bow +7
[Quest]Apostle-personal staff+7 and pole +7
[Quest]Uruk Hai - personal shield+7
[Quest]Lard Orc - Perspnal mace+7
And this personals will be not tradable and not upgradable and drop rate will be maybe 20%/30% of each personal.
It will be nice to use your own personal dagger +7:D
