Genshin Impact is a massive game, filled with exploration and wonder. Go about on your travels, find wandering NPCs who might give you a little story of the land, or perhaps even a quest to solve for some rewards! There is always something to do in the land of Teyvat; however, some things you can only do a few times a day because of the Original Resin consumable! Don't worry, though, as this regenerates over time! One thing you use Original Resin for is collecting rewards after finding a Ley Line. In the Mondstadt region, there are two of these, the Blossom of Wealth and The Blossom of Revelation, but what exactly are they?
Ley Lines are a type of mini-boss that spawn a few waves of monsters, and by defeating all of the monsters, a Ley Line Blossom will be revealed. However, you have to pay 20 Original Resin to unlock the rewards inside the Ley Line Blossom.
These Ley Lines only become available to you once you hit certain Adventure Rank thresholds. To unlock the Blossom of Revelation, you have to be Adventure Rank 8 and to reveal the Blossom of Wealth, Adventure Rank 12 is required. Once they have been unlocked, when looking at the map, you'll be able to locate these quite easily, as they are pretty colorful, and they are always there.
If you choose to open the Ley Line Blossom, it will award you with Adventure Rank EXP, Friendship EXP, and depending on what Ley Line you went to, Character EXP Materials for Blossom of Revelation or Mora for Blossom of Wealth. The rewards will always scale to your Adventure Rank, so the higher your rank is, the better the loot will be! Even if you defeat one, they will move locations, so head to the new place, and you can defeat them again! Dependent on your Original Resin count, of course!
