How to Reroll with a Tempmail and if It's Worth it
The short answers is no .
HoYoverse does not have a guest account system; multiple emails are needed for rerolling.
In-game cutscenes are unskippable.
It takes about 30 minutes to unlock the Gacha system with each reroll.
Star Rail Pass rewards from pre-registration can only be used on standard banners, not on limited banners.
The 5-Star pull rate is only 0.6%.
If you're still here, then I think this meme is perfect for you:

Step 2 : Log into the game with the email you just made.
Step 3 : Complete the prologue until the Gacha and pre-registration rewards are available, which takes approximately 30 to 40 minutes.
Step 4 : Use 20 rolls on either the Departure Warp Banner or the Stellar Warp Banner .
Step 5 : If your pulls aren't ideal. Exit to the home screen, log out, and repeat step 1 .
Given the tedious nature of rerolling, it's best to aim for any 5-Star character, as well as 4-Star characters to help you start your adventure; once you obtain a 5-Star, it's advisable to stop rerolling.
