Change race
No due to story and how hard coded it is.
You can not change the race. Only way to “change” is to delete current character and start completely new one. You will lose all soulbind items when doing that.
Unless your character is very low level i would not delete it. Each character in this game get birthday gifts for each year in game and those are very good to get.
You can not change race, but you should have more character slots and can make a new character with the race you want. In gw2 alts are a big thing and it is always good to have more then one class. If you don’t have a slot left, then you can buy a slot from the gem store.
As others have said, there is no item to change your character’s race “after” you have started playing.
At launch, this was something that was discussed as a design decision. They stated that they didn’t want players to be able to just change race willy nilly, and wanted people to actually have to think about which race they wanted to play, and to have the choice mean something. And by mean something, they meant story wise, cosmetically, and flavor. They did not want to class lock by race, or make racial skills a “big thing” so as not to pressure players to play specific races for specific purposes.
Eventually, after multiple race change requests, the developers told us that it just wasn’t physically possible to implement any type of race change into the game due to how the system was coded. The potential game breaking bugs outweighed any benefit to the item. Not to mention the recoding that would have to occur.
