Guild Wars 2

https://api.guildwars2.com/v1/item_details.json?item_id=20268

This item, “Boxing Gloves,” has a buff listed in the infix_upgrade with only a skill_id, no description. I’m not sure if this is actually an error, or if it’s intentional, but it’s certainly unexpected.

Normally the buff looks like this:

          "buff":
            {
              "skill_id":"[number]"
              "description":"[string]"
            }

On one hand, you could say that if there’s no description, then there’s no use knowing the skill_id. On the other hand, you could say that it’s still worth knowing that there is a buff of some sort on the item. I don’t know which way is best.

In any case, it’s still good to know that this is normal/intentional and not a bug in the API so we can work around/with it.
