[1.5.10] Crafted randart trinkets become purple

[Effigy]

If you use the Assassin Lord crafting bench in the Strange Cave to modify a randart trinket, it can have its rarity reduced to purple (i.e., not unique anymore). I only tried this with a psychoportation torque, but I assume the same issue exists for other torques/totems/wands. I would expect the modified item to maintain its rarity, as is the case with other item types modified with the crafting bench.

do not use the crafting bench to modify trinkets anyway, there is so many ways it can go wrong
