[Tip] Quick Character reroll guide
There are 2 ways of character reroll in Genshin. Lv.5 reroll & Lv.7 reroll. Lv.5 reroll can try Beginner's wish for 10 times (or Standard wish for 10 times) Lv.7 reroll can try Beginner's wish for 20 times (or Standard wish for 10 times) + Ballad in Goblets for 10 times. Lv.5 takes 15min, Lv.7 takes 30min to reroll. If you're gonna try to reroll, my recommendation is Lv.7. Let's see how to do it.
First, follow the guide but ignore the slime monster. Keep going further and you'll find a chest. Get and open in (Lv.5 reroll doesn't need to do this)
Slay the monsters camp ahead and open another chest.
Keep following the guide and you'll find a girl who gives a cooking quest. She asks to cook food. You can get the ingredients from the barrel next to her. Clear the quest. (Lv.5 reroll doesn't need to do this)
Check the waypoint of the town and clear the Stormterror quest. It's very easy.
Once you clear the quest, the guide says enter the knights of Favonius HQ. Lv.5 reroll, just follow the guide and enter the HQ. Lv.5 reroll ends here. Try Beginner's wish for or Standard wish for 10 times. If you're not satisfied with the result, do reroll and repeat. Lv.7 reroll, need to do something before you enter. Check this out.
Climb the wall and go to the rooftop of the HQ building. There are 2 chests on the rooftop. They're easy to find so get and open them.
There's a waypoint on the rooftop as well. Activate the waypoint before you go down. If you found 2 chests and 1 waypoint, your work is done here. Go to the HQ.
Keep following the questline. You'll enter the temple. Get Amber and charge the flame arrow to burn thorn vines. Full-charged flame arrow will burn them and the vines will be disappeared. You can find a chest behind the vines easily from the right side. There's one more chest that is hiding behind the boxes after this. Once you've slain the pack of monsters, you can find some boxes on the left side. Burn them and get another chest.
After clear the temple, go to the west. You'll find a chest that surrounded by small thorn vine. Get Amber and burn the vines. Open the chest.
Keep going ahead. You'll find 3 flying slimes there. Shoot them with Amber's arrow. If you kill all of them, you'll get a reward. In the same place, there's a small blue sphere as well, called Anemoculus. Use glider wings from the top of the rock and get it.
Head to the Statue. Activate it and choose the option 'Offer All'. It will consume your items and increase your EXP.
Climb the giant tree behind the statue. You can find another Anemoculus on the right side of the branch, where I stand. (I've already taken it)
Go ahead behind the giant tree. You'll find some kind of wind spirit on the ground. Approach to the spirit and it will grant you a short buff. If you use any wind skill with this buff, it will cause wind field. Use Traveler's E skill to create wind field. Jump on the wind field and you can fly high to approach Anemoculus in the air. Get it.
When you activated Statue, you might saw a cutscene that a ruin gets activated as well. Go to the ruin. It activates wind field so get there and jump. You'll fly really high. Near the top of the wind field area, there's another Anemoculus. Get it before you move.
You'll find another temple easily from the wind field. Enter the temple.
Now you can control Lisa. Destroy the boxes in front of Lisa. There's a hidden space behind it and you can find a chest. Open it. There's one more chest in the Fire Slime area. Get that chest as well. You can find the 3rd chest in 4 fire slime area behind the cage, but not really needed.
Clear the temple. You'll find another Anemoculus next on you easily.
If you get the last Anemoculus, teleport to any statue and select 'Offer All' again. You might reach Lv.7.
Teleport to the town and go to the Adventurer's Guild NPC. She'll give you level up rewards. Claim all.
Time to check your result. Go to the 'Shop' tab > Paimon's Bargains > Stardust Exchange > Acquaint Fate. You can exchange 3 of them. Exchange it. Now you have enough currency to try Beginner's wish for 20 times (or Standard wish for 10 times) + Ballad in Goblets for 10 times. Use all of them. If you're satisfied with the character result, keep play the game. If you're not, time to repeat all these processes. Good Luck!
