If you're just starting out in Genshin Impact along with everyone else, then you are likely considering whether or not it is worth it to look for specific or high star characters. Well, if you are wanting to min-max, or you want to play the game seriously without spending too much money, it can be worth it to try to start out with the best options available to you.
How to Reroll for Characters
Rerolling in Genshin Impact can be accomplished by creating multiple accounts with a username only. You can head to this link, and create a Mihoyo account with just a username and not an email address. You can then login to the game, head to level 5 or 7 to receive a currency that allows you to purchase characters. If you don't get the one you want, just create a new account and restart the process!
Leveling to these early milestones will take about 20 minutes for level 5 and 45 minutes for level 7. It is really up to you if you want to spend all of that time attempting to get the character you absolutely want. Once you have reached rank 5, you will get 10 Acquaint Fates in the mail. These are a currency used to purchase from the character pages under the characters tab!
If you want to head to level 7, then this will open up the possibility of obtaining Venti, which is look at as the best character in the game. He has a limited time banner, that only uses the Intertwined Fates currency. You don't get these for free, but you can purchase them with the 1,600 Primogems that you acquire for free by hitting Adventure Rank 7.

If you're determined to run through as many times as you can to get a 5-star or obtain Venti, then here's a speedrun with the best route for reaching Adventure Rank 7:
What Should I Reroll to Get?
Venti is supposedly the most powerful character in the game currently, so he would be one of your targets. As mentioned, he requires you to reach level 7, which takes about double the amount of time to get to. If you just want a strong character, then leveling to 5 and looking to get a 5-star is going to be the best bang for your buck. Trying to get a specific 5-star will be quite difficult, so just be happy you have a 5-star at all and start using that account.
Will Rerolling Get Me Banned?
There's been different takes on this and some are saying that it's fine and others are saying you could get banned. The official word, according to Demone Kim on YouTube, is that it is discouraged and you might get banned. However, this has also been disputed by many people, saying that they were only referring to people selling accounts. So, I know this is not a great answer, but we don't know for sure. This is a do it at your own risk sort of thing, and hope that nothing happens!
