Recently I have seen a few people going on about equipment resetting on them so I thought that when a 2x drop eb promo happens (that drops aqua and inferno), there is also a 2x chance of success when enchanting equipment. First I had thought it should only be 2x success rate on the equipment from the 2x eb (if enchantable) but then I thought it would take a long time for the eb you need to be 2x drop.
