What is currently safe to say
Ravemount is a named boss, not a full solved farm
Community pages repeatedly surface Ravemount as a boss lookup term, and one community wiki summary ties it to a cathedral-boss change. That is enough for a search route, but not enough for a fake guaranteed-farm guide.
If you are searching this boss by name, use Ravemount as a source-labelled entity page first, then go back to the dungeon hub for route context. Avoid treating community drop or spawn claims as official until the game or a creator-owned post confirms them.
