I am new on poe2 have some questions

1-When the game is released after early access, what will be transferred to the items in the warehouse, previously purchased costumes or dropped items?

2-Is it possible to create more than 1 character in Poe2? Are the storages shared?

3-What happens to the characters at the end of the season? I couldn't spend much time and progress. Is there a chance to continue with my character? Do I have to create a new character?

4-Are skins purchased from the market tied to a single character or are they transferred and removed for each character?

5-Finally, a question. Is it possible to make irreversible mistakes while upgrading my character?

1. All items and characters are usually transferred to Standard after a league reset. Since we are already on standard its the same. Not enough info still. They might be wiped or have their own server after EA.

However micro transactions are perm. they will go with you anywhere like cosmetics / storage (not the items in storage)

2. Yes. Yes.

3. Gets transfered to Standard (What you are on right now, so nothing). Yes you can continue on as normal.

4. Every Character can wear your purchased items.

5. Yes. right now you can choose the wrong Ascendancy and the act 3 quest venom drought are both perm.
