If you have two of the same breed of item (two Quickdraws, two Longswords, etc.) they will count exactly the same for Weapon Sentimentality, despite having different materials, enchants, or weapon parts. To reproduce this, do as follows:

1. Have current weapon in weapon slot with full sentimentality
2. Swap in the same breed of weapon on the equipment screen or on the item belt mid-combat
3. Enjoy having a bloodhunt enchant/extended pole against a dodgy foe or a vorpal enchant/curved pole against a tank as needed.

This isnt a bug, lol. Thats how the Trait works.

It doesnt matter what the mats, enchants or weapon parts are. The Trait only requires your Main Hand to be the 'Same Weapon'.

It tracks based on the item type rather than the specific item instance, for simplicity and convenience's sake.
