To obtain a Silver Raven Insignia, you need to find and kill Treasure Hoarders at Level 40+. Anything above Lvl 40+ also has a chance to drop Treasure Hoarder Insignia.
You can get these from any Treasure Hoarder you kill, no matter how they look or what they use to attack you. These Hoarders tend to roam around Liyue, though you can encounter them in Mondstadt during the Story Quests with Amber and on the outskirts of Dragonspine; Liyue is where they spawn.
To get Treasure Hoarders to become Lvl 40+, you need your World Level to become World Level 2 or higher. The most efficient WL to farm is WL 4, as enemies are between Level 42 and 62. This will give you the most consistent enemy Lvl past 40+.
To get to WL 4, you need to have completed the following.
- Be on World Level 3
- Be Adventure Rank 35
- Clear Ascension Quest 2
The fastest way to get around is to use the Waypoints, kill everything in sight, and then move on. You can farm these about every two days; they do not respawn as quickly as monsters.
The image below is where you can find Treasure Hoarder Insignia in Liyue. The Golden Insignias are where the Hoaders spawn.
