Will the levels remain if I buy the battlepass now?

I'm in Fortnite level 100 and do i have to re-level the battelpass?

If you buy the BP now, you have already unlocked everything up to level 100, but I would not advise you to spend money on Fortnite.

Yes the Battlepasss level remains. You even get the rewards for the levels you have earned

Ok so all V-Bucks for the next Battle pass and all skins or dances ep boosts and so on?

I don't quite understand what you mean. For one, everyone can play what they want. And secondly, the BP does not automatically get all levels up to 100: /

Which level are you at?

My answer. Back then I spent money on it and now I don't play it anymore. So better leave something like that. It doesn't bring anything anyway. You still have all the rights like the others.

If you are already level 100 or more, it doesn't matter whether this season or next. If you are only level 50 or so it is more worthwhile to buy the BP next seaspn

Level 100 at no battle pass because it can't go on

Usually all such passes are structured identically, you can earn levels and you can buy / earn additional rewards with such a pass.

Assuming a BP has 120 levels and you already have 100 of them, you will receive all rewards up to the BP level you have reached without having to earn them again. So in one fell swoop you will get everything you would have received up to that point if you had the BP from the beginning.

You have to decide for yourself whether the financial effort is worth it, I personally do not spend any money on such passports because ultimately they are only cosmetic items that you can hardly see yourself.

I didn't say he shouldn't play Fortnite, I just advised him not to spend money on the game because I personally spent a lot of money on the game and now regret it.
He is now level 100 and asks if he already gets the rewards for level 100 if he buys the BP (if I misunderstood please correct me)
