Genshin Impact : Black Crystal Horn

To obtain a Black Crystal Horn, you need to find and kill Mitachurls at any level. Upon eliminating these fighters, they have a chance to drop Black Crystal Horns. Anything above Lvl 60+ also has a chance to drop Heavy Horn and Black Bronze Horn.

To get Mitachurls to become Lvl 60+, you need your World Level to become World Level 5 or higher. The most efficient WL to farm is WL 6, as enemies are between Level 64 and 84. This will give you the most consistent enemy Lvl past 60+. Anything below, you will find them, but not as often.

To get to WL 6, you need to have completed the following.

• Be on World Level 5
• Be Adventure Rank 45
• Clear Ascension Quest 3

You can get these from any of the Mitachurl family, no matter the Element or the size.

The fastest way to get around is to use the Waypoints and travel around the entirety of Teyvat. Kill everything in sight, and then move on. The images below are the locations you can find Mitachurls.
