There are many times when you might want to try and skip tutorials. Maybe you’ve played similar titles or previous entries. In a gacha game, you could want to skip past those early missions so you can try and reroll to get a more ideal initial character or two. In the case of Honkai: Star Rail, you can’t skip the tutorial and must go through all of the “Today Is Yesterday’s Tomorrow” Trailblaze Missions every time you play, which would mean trying to reroll can take a lot of time.
This basically means you’ll need to go through most of the first six sub-missions, many of which act as a tutorial, in the initial Trailblaze Missions any time you might try to restart Honkai: Star Rail. Depending on how much you explore and due, this could take anywhere from 30-60 minutes. Your first tutorial gacha pull is also always a single pull on the basic banner.
Once you can do your first 10-pull in Honkai: Star Rail which will only cost 8 Star Rail Passes if you’re using the promotional Departure Warp Starter Warp, you’ll have your chance of getting your first five-star character. The featured five-star characters you might get from it are Bailu, Bronya, Clara, Gepard, Himeko, Welt, and Yanqing. All seven of them are always available. However, the deal on that banner is you can do a total of five 10-pulls, getting you 50 characters and Light Cones. By the end of it, you are guaranteed one of those seven five-stars characters. (I got Bailu, for example.)
However, it takes a very substantial amount of time to earn enough for all those pulls. (I was at Trailblaze Level 10 by the time I did.) So if you did want to reroll in Honkai: Star Rail, the best time would be after the tutorial when you get access to the Departure Warp. On normal banners, it takes 90 pulls to get a guaranteed five-star character or Light Cone, with there being a 50/50 shot of it being the focus one or one from the general pool. Your odds of getting a five-star is 0.6%. A reroll will require you to make an entirely new HoYoVerse account, restart, and go through the tutorial until you can take part in the gacha again.
Honkai: Star Rail is available for PCs and mobile devices, and PS4 and PS5 versions are in development.
