From my understanding, this is how lootboxes in Overwatch are populated: first the rarity of the 4 items is chosen, for example 3 Common items and 1 Uncommon item, then for each of the 4 items, a random cosmetic is picked out of the ones you don't already own.

Does this hold when time-limited event lootboxes are involved? If I've purchased all items not restricted to events before a new event is released, will I only receive event-related items from lootboxes, only finding duplicates of one rarity after receiving all event items of that rarity?

If we look to the patch notes, it clearly states that

we’re drastically reducing the amount of duplicates you will receive when opening loot boxes.

As such, I think it's safe to trust the commenters that it's possible to get duplicates, but they are very rare. It does not say that they've eliminated duplicates.

I have personally gotten duplicates post-Doomfist, but maybe 2 or 3 from around 30 loot boxes.

Edit: here are some players reporting duplicates on the forums. Note that they aren't mentioning exactly what was a duplicate or exactly what they had before they opened the boxes.

  • I don't see anywhere where those users specifically said, "I had all the commons so I finally got a duplicate common" or anything similar for the other rarities. A few people reporting duplicates said that they had "most" of the items, but not that they only got a duplicate blue because they had all the blues. I'm not convinced it works that way. – cottog Aug 28 '17 at 14:10

  • Thanks, I'm aware of that happening, it happens when you already own all event items of a certain rarity and you roll an event item slot of that rarity. It does not go against the theory in my question. – Wrigglenite Aug 28 '17 at 15:30
  • That user specifically said that was not the case in their replies to the linked comment. – cottog Aug 28 '17 at 15:39
  • SInce this answer has always been wrong, and by now everyone should've noticed, would you mind going ahead and deleting it? – Wrigglenite Nov 20 '18 at 10:18

The short answer is


The long answer is that there are separate drop tables for event items and regular items, but the game rolls for the loot table (event or regular) first, then rolls on that loot table for the actual item.

The standard rules apply, though. At least one item will be an event item and at least one item will be Rare quality or better.

On a side note, the event drop table has a higher chance for its Legendaries than the standard loot table does for its Legendaries.


Event items work similary to non-event items in this regard. If you own every non-event item of a specific rarity but are still lacking event items, items of that rarity from event lootboxes will only be event items. After obtaining all event items of that rarity, duplicates will start appearing, both of event and non-event items.

The opposite is not true, however. Owning all event items of a specific rarity while not owning all non-event items of that rarity will still make it possible to find event duplicates in lootboxes. This is due to event lootboxes containing at least one guaranteed event item.
