Individual items or item groups can also have different drop rates. It's possible for a 'rare' item to have a lower chance to drop than an 'epic' item, or less of a chance than another rare item in the same loot table. Also, most of the potential vial drops are from a loot table that only has the vial, which wouldn't be affected by rerolls.
