If the game tries to spawn a unique but (1) there either isn't a unique of that type, or (2) all uniques of that type have too high a level to be picked, or (3) it picks a unique of that type and that unique has already spawned in that game, the unique will instead be a rare with 3x durability.
The first two criteria also apply to set items, which become magic items with 2x durability.
