Question about adding a second Minecraft profile to Wynncraft account

Hi,

I have a question about the “Profiles” section on the Wynncraft website.

If I add a second Minecraft account/profile to my Wynncraft account and then set that new profile as the primary one, what happens to the in-game progress?

Would the characters, levels, quests, bank, items, professions, etc. remain the same under the new primary profile, or would the new Minecraft account start completely fresh in-game?

The page says that selecting a primary profile updates the Wynncraft account username and rank, but I am not sure whether this affects only the website/rank information or also the actual in-game progress.

I just want to understand how it works before changing anything.

Thanks in advance.
